With over ten years of K-series swap experience behind it, the Hybrid Racing K-swap conversion harness is one of the most widely used and trusted conversion harnesses in the game. It's wired thousands of K-swaps around the world, and it takes the single most intimidating part of the build and turns it into plug-and-play.\u003c\/p\u003e\n\n\u003ch4\u003eWhat A Conversion Harness Actually Does\u003c\/h4\u003e\n\n\u003cp\u003eQuick clarity, because it matters when you're buying. This is a conversion harness, not an engine harness. Your K-series engine harness is the one that lives on the motor itself. This conversion harness is the bridge that ties that engine harness, your K-series ECU, and your car's factory chassis wiring together, so an engine that was never meant for your Civic or Integra can talk to it properly. It's the adapter that makes the whole swap communicate, and getting it right is the difference between a clean startup and chasing gremlins for months.\u003c\/p\u003e\n\n\u003ch4\u003eWhy This Harness Over The Others\u003c\/h4\u003e\n\n\u003cp\u003eHere's what sets us apart from the other names in this space. Our conversion harness ships fully assembled and ready to install. You're not sending us a chunk of your factory harness and waiting weeks for it to come back, the way some companies require. It shows up complete, often with overnight shipping available, so your build keeps moving instead of stalling out waiting on wiring. It plugs directly into your factory dash harness, your OEM K-series engine harness, and your K-series ECU, and it keeps full functionality of your factory gauge cluster. It also comes with a full replacement warranty and real tech support, so if you hit a snag mid-swap, there's someone who knows these harnesses on the other end.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt Right, So It Lasts\u003c\/h4\u003e\n\n\u003cp\u003eA conversion harness is not the place to cut corners, because a bad one haunts a build for years. We build every harness with brand-new connectors, terminals, and wire sourced from the same manufacturer Honda uses, so it's genuine quality throughout. Every harness is machine-made for consistency and then checked by a human before it ships. There are no soldered joints anywhere, and every wire is clearly labeled, so your install stays clean and you're never guessing what goes where.\u003c\/p\u003e\n\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\n\u003cp\u003eThis conversion harness fits the 1992-1995 Honda Civic (EG), 1993-1997 Honda Del Sol, and 1994-2001 Acura Integra (DC2 and DC4).

When in doubt, call us before you order and we'll sort out exactly what your combination needs.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003eBuilt for K-series swaps in the 1999-2000 Honda Civic (EK chassis, EM1 Si included)\u003c\/li\u003e\n    \u003cli\u003eWorks with USDM and JDM 02-04 K-series engine harnesses and ECUs (K20A, K20A2, K20A3)\u003c\/li\u003e\n    \u003cli\u003eRetains full factory gauge cluster functionality\u003c\/li\u003e\n    \u003cli\u003eTrue plug and play: no cutting, splicing, or core harness exchange\u003c\/li\u003e\n    \u003cli\u003eAll-new connectors, terminals, and wiring from Honda's own supplier\u003c\/li\u003e\n    \u003cli\u003eMachine-crimped, no soldered joints, human-checked before shipping\u003c\/li\u003e\n    \u003cli\u003eEvery wire labeled for a clean, organized install\u003c\/li\u003e\n    \u003cli\u003eFull replacement warranty\u003c\/li\u003e\n    \u003cli\u003eFree phone and email tech support from people who've wired these swaps for a decade\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1999-2000\u003c\/td\u003e\n            \u003ctd\u003eHonda\u003c\/td\u003e\n            \u003ctd\u003eCivic\u003c\/td\u003e\n            \u003ctd\u003eEK (all trims, EM1 Si included)\u003c\/td\u003e\n            \u003ctd\u003eK20 swap (02-04 harness\/ECU)\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis harness is chassis and year specific.

We stock all of it, and if you're starting from zero, our K swap packages bundle the big pieces so nothing shows up incompatible. The single most common mistake we see is buying a 05-06 or K24 engine harness to save money and expecting it to work with this conversion harness. It won't. Match the harness and ECU to 02-04 K20 spec and the wiring day of your swap becomes the easy day.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); font-weight: var(--bs-body-font-weight); text-align: var(--bs-body-text-align);\"\u003e1999-2000 Honda Civic with K-Swap \u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); font-weight: var(--bs-body-font-weight); text-align: var(--bs-body-text-align); font-style: italic;\"\u003eIf your 1999-2000 Civic came with a D16y5 engine, most commonly found in the HX model, you will need to use the \u003c\/span\u003e\u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/hybrid-racing-k-series-conversion-harness-for-96-98-civic?_pos=1\u0026amp;_sid=66591edda\u0026amp;_ss=r\" target=\"_blank\"\u003e96-98 Conversion Harness\u003c\/a\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); font-weight: var(--bs-body-font-weight); text-align: var(--bs-body-text-align); font-style: italic;\"\u003e.\u003c\/span\u003e\u003cbr\u003e\n \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n   \n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Conversion Wiring Harness\u003cdiv\u003e(4) Zip Ties\u003c\/div\u003e\n\u003cdiv\u003e(1) Wiring Connector Pack\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/HYB-CWH-01-19_-_HR_99-00_Civic_K-Series_Conversion_Wiring_Harness.pdf?v=1594905377\" target=\"_blank\"\u003eView Install Guide HERE\u003c\/a\u003e\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"Hybrid Racing","offers":[{"title":"Default Title","offer_id":48940790020,"sku":"HYB-CWH-01-19","price":219.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/HYB-CWH-01-19_1.jpg?v=1785967674"},{"product_id":"hybrid-racing-k-series-conversion-harness-for-01-05-civic","title":"Hybrid Racing K Swap Conversion Harness for 01-05 Civic Non-Si","description":"\u003cul\u003e\n\u003cli\u003ePlug and play K-Swap conversion harness! \u003c\/li\u003e\n\u003cli\u003eBrand new connectors and pins sourced from the same company Honda uses. \u003c\/li\u003e\n\u003cli\u003eFree phone and email tech support. \u003c\/li\u003e\n\u003cli\u003ePowering 1000's of K-Swaps world wide! \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- split --\u003e\n\u003cul class=\"tabs\"\u003e\n\u003cli\u003e\u003ca class=\"active\" href=\"#Description\"\u003eDescription\u003c\/a\u003e\u003c\/li\u003e\n \u003cli\u003e\u003ca href=\"#VehicleFitment\"\u003eVehicle Fitment\u003c\/a\u003e\u003c\/li\u003e  \u003cli\u003e\u003ca href=\"#TechnicalData\"\u003eTechnical Data\u003c\/a\u003e\u003c\/li\u003e   \u003cli\u003e\u003ca href=\"#Included\"\u003eIncluded\u003c\/a\u003e\u003c\/li\u003e  \u003cli\u003e\u003ca href=\"#InstallGuide\"\u003eInstall Guide\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e\n\u003cul class=\"tabs-content\"\u003e\n\n\n\u003cli class=\"active\" id=\"Description\"\u003e\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/DAWKumigBZ0\" title=\"YouTube video player\" style=\"width:100%;aspect-ratio:16\/9;height:auto;border:0;display:block;\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\n\n\u003ch3\u003eHybrid Racing K-Swap Conversion Harness - 2001-2005 Honda Civic (EM2 \/ ES1)\u003c\/h3\u003e\n\n\u003cp\u003eWiring is the part of a K-swap that stops people, and it's the part this solves. With over ten years of K-series swap experience behind it, this conversion harness is one of the most widely used on the market, and it's wired thousands of swaps worldwide.

Your engine harness is the one that lives on the motor. This conversion harness is the bridge between that engine harness, your K-series ECU, and your Civic's factory chassis wiring, letting an engine your car never came with talk to it properly. It's the translator in the middle, and getting it right is the difference between a clean first start and months of chasing gremlins.\u003c\/p\u003e\n\n\u003ch4\u003eWhy This One Over The Alternatives\u003c\/h4\u003e\n\n\u003cp\u003eHere's what separates us from other companies in this space. Our conversion harness ships fully assembled and in stock, ready to go out the door, often with overnight shipping available. You're not mailing in part of your factory harness and waiting weeks for it to come back modified. No core required.\u003c\/p\u003e\n\n\u003cp\u003eIt plugs directly into your factory dash harness, your OEM K-series engine harness, and your K-series ECU, and it keeps full functionality of your factory gauge cluster. It also comes with a full replacement warranty and real tech support, so if something doesn't make sense mid-swap, there's someone on the other end who knows these harnesses.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt To Not Cause Problems Later\u003c\/h4\u003e\n\n\u003cp\u003eA conversion harness is not the place to cut corners, because bad wiring haunts a build for years. Every harness is built with brand-new connectors, terminals, and wire sourced from the same manufacturer Honda uses. Each one is machine-made for consistency and then checked by a human before it ships. There are no soldered joints anywhere, and every wire is clearly labeled, so your install stays organized and you're never guessing what goes where.\u003c\/p\u003e\n\n\u003ch4\u003eCheck Your Engine Harness Before Ordering\u003c\/h4\u003e\n\n\u003cp\u003eCompatibility comes down to what's on your motor, not what's in your car.

Every harness is machine-assembled and then hand-inspected before it ships. There are no soldered joints anywhere in the harness. Solder joints crack under heat cycling and vibration; this harness uses crimped, sealed terminals throughout, which is the correct method for an automotive environment.\u003c\/p\u003e\n\n\u003cp\u003eHybrid Racing has been making this harness for over ten years, and it's been used in thousands of K-swaps worldwide.

You'll need your K-Series engine harness already attached to the engine, your EF dash harness in good condition, and a compatible K-Series ECU relocated to your EF's ECU mounting location. The conversion harness routes between the firewall and ECU area, connecting the EF dash harness plugs on one end and the K-Series engine harness and ECU plugs on the other. All wires are labeled, so you're not guessing which connector goes where. A full installation guide is not included in the box, but Hybrid Racing's tech support can walk you through any step of the process.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this harness work with a K24 swap in an EF chassis?\u003c\/strong\u003e\u003cbr\u003e\nNo. This harness is built for 02-04 K20A, K20A2, and K20A3 engine harnesses only. K24 harnesses and ECUs have different pinouts and are not compatible with this conversion harness.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to send in my factory EF harness?\u003c\/strong\u003e\u003cbr\u003e\nNo. Unlike some competitors who require you to ship in your OEM harness for modification, this harness arrives fully assembled and ready to install.

Version 2 was built around a more universal chassis layout and more flexible harness routing. You can run this K-Series tuck engine harness across the center of the firewall like an OEM K-series harness, or swing it more to the right side compared to Version 1. That routing style works especially well if you’re running a Rywire harness for RHD cars, but it still fits and functions just fine on LHD shells too. Version 2 also gives you more room around aggressive headers, so you’re not melting loom every track day.\u003c\/p\u003e\n\n\u003ch4\u003eQuality connections, real-world layout\u003c\/h4\u003e\n\u003cp\u003eEvery Rywire K-Series harness is warrantied and guaranteed to work, and you get actual install and troubleshooting help over the phone to back that up. Because of that, and like most wiring, this K-Series Budget harness purchase is non-refundable—so make sure this is the layout you want before you hit buy.\u003c\/p\u003e\n\n\u003cp\u003eThis Budget K-Series harness Version 2 (K2) wire tuck layout is nearly identical to the K2 Mil-spec Rywire K-Series harness. The big changes are the wire type, the single black wire color, and the expandable loom. All connectors and materials are brand new—no crusty reused plugs, ever. Rywire K-Series harnesses use pneumatic crimping for every connector so you get a proper OEM-style crimp every time, and each plug gets a white ID label to make install and diagnosis way less annoying.\u003c\/p\u003e\n\n\u003cp\u003eHigh-interference circuits get proper shielding, routing, and grounding to keep noise out of your ECU. Every harness gets 100% tested pin-to-pin and resistance checked to confirm there are no sketchy drops or spikes in voltage.

Then you need to wire up the VTEC side of things, or your\n  shiny new B16A is just an expensive non-VTEC motor. Your original 88-91 OBD0 wiring came set up for a\n  D-series, so it doesn't have the wires for the VTEC bits that make a B16A worth swapping in the first\n  place. That's what this Rywire subharness handles. It adds the wiring your ECU needs to actually run\n  VTEC, so the engine hits that second cam and pulls hard up top the way it's supposed to. It's a clean,\n  plug-in piece of the swap instead of a night spent splicing wires by hand.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat This Subharness Actually Wires Up\u003c\/h4\u003e\n\u003cp\u003e\n  Here's exactly what it adds to your harness, and why each one matters. It wires in your VTEC solenoid,\n  which is the part that actually engages VTEC, no solenoid wiring, no VTEC, simple as that. It connects\n  your VTEC oil pressure switch, so the system knows it's got the oil pressure to safely flip over to the\n  high cam. It hooks up your knock sensor, which is cheap insurance that helps protect your motor from\n  detonation. And it ties in your second oxygen sensor so your fueling stays happy.

So instead of\n  hacking your factory wiring apart to make everything line up, you plug the adapter in and let it do the\n  translating.

The motor's the easy decision, the wiring is where people get stuck. This\n  Rywire conversion harness takes that headache off your plate. It lets you run a 2002-2004 RSX engine\n  harness in your Civic by repositioning the wires that need to move and plugging straight into the stock\n  20-pin gray connector on the interior side of your engine harness. So instead of rewiring your car from\n  scratch to make a K20 talk to a chassis that came with a D17, you use a proven RSX harness and this\n  adapter bridges the gap. It's the clean way to handle the electrical side of one of the most popular\n  Honda swaps out there.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat It Actually Does\u003c\/h4\u003e\n\u003cp\u003e\n  Let's be clear about how this works, because that's what matters when you're planning a swap. Your Civic\n  has a factory 20-pin gray plug on the interior side of its engine harness, and this conversion harness\n  connects right to it. From there, it repositions the necessary wires so a 2002-2004 RSX engine harness\n  drops into your Civic and works the way it should. That's the whole trick: it adapts the RSX engine\n  harness to your Civic's existing connector, so you get a tidy, factory-style connection instead of a\n  bundle of splices and tape behind your dash. It plugs in where it's supposed to and leaves your wiring\n  looking like it belongs there.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhy This Is The Way To Wire It\u003c\/h4\u003e\n\u003cp\u003e\n  The 01-05 Civic K-swap is a rite of passage for a reason, it's a light, cheap chassis that comes alive\n  with a K20 in it. But the wiring is the part that scares people off or turns into a weekend-killer. Going\n  the RSX-harness route with this conversion harness keeps the whole thing clean and repeatable: you're\n  using a known engine harness and a purpose-built adapter instead of cutting into your car and hoping you\n  got every wire right. That saves you time and frustration, and it leaves you with a swap you can actually\n  trust, so you can spend your energy on the fun parts of the build instead of chasing wiring gremlins.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRywire K-swap conversion harness for the 2001-2005 Honda Civic\u003c\/li\u003e\n  \u003cli\u003eConnects to the factory 20-pin gray plug on the interior side of your engine harness\u003c\/li\u003e\n  \u003cli\u003eRepositions wiring to run a 2002-2004 RSX engine harness in your Civic\u003c\/li\u003e\n  \u003cli\u003eClean, factory-style connection with no custom rewiring of your car\u003c\/li\u003e\n  \u003cli\u003eBuilt by Rywire for reliable, repeatable K-swap wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2001-2005 Honda Civic DX\u003c\/li\u003e\n  \u003cli\u003e2001-2005 Honda Civic LX\u003c\/li\u003e\n  \u003cli\u003e2001-2005 Honda Civic EX\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Rywire K-swap conversion harness for the 2001-2005 Honda Civic.

OBD1 ECUs (like the P28, P30, P72, and P61) are the go-to base for chipped or socketed tuning.

To complete a full OBD0 to OBD1 conversion, you'll also need an OBD1 distributor, a 4-wire OBD1 oxygen sensor, and the OBD1 ECU itself. If you're adding VTEC, make sure your engine has the corresponding solenoid and pressure switch already installed before wiring through the pigtail.\n\u003c\/p\u003e\n\n\u003ch4\u003eInstallation:\u003c\/h4\u003e\n\u003cp\u003e\nPlug the OBD1 side of the harness into your ECU and the OBD0 side into your existing chassis harness.

Your OBD2 distributor's not going to plug into your OBD1 engine harness. The connectors are different. You need a distributor jumper harness to make them work together. The SpeedFactory OBD1 to OBD2 distributor jumper harness plugs into your OBD1 engine harness on one end and your OBD2 distributor on the other end. No cutting wires, no soldering, no guessing which wires go where. You plug it in and it works.

OBD2 distributors use a bigger 10-pin rectangular connector. When you're swapping an OBD2 engine into your OBD1 Civic, Integra, or CRX, your engine harness has the OBD1 round connector but your OBD2 distributor has the 10-pin connector. They don't match. You can't plug them together. The SpeedFactory jumper harness converts your OBD1 connector to an OBD2 connector so your distributor actually plugs in.\u003c\/p\u003e\n\n\u003ch4\u003ePlug It In and You're Done\u003c\/h4\u003e\n\n\u003cp\u003eYou don't need to cut or splice anything. One end of the harness plugs into your OBD1 engine harness where your distributor connector is. The other end plugs into your OBD2 distributor. That's it. You're not stripping wires, you're not soldering, you're not crimping connectors. You plug it in and your distributor works. The connectors are OEM-style with proper metal pins, so they don't come loose or cause intermittent misfires like cheap connectors do.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt with Real Automotive-Grade Wire\u003c\/h4\u003e\n\n\u003cp\u003eSpeedFactory makes this harness with automotive-grade wire that's the correct gauge for ignition signals. It's not some cheap wire that's going to crack or corrode. The insulation's proper automotive-grade stuff, and the connectors are metal pins like OEM connectors.

The problems: pin damage is easy, wire length is often too short to make clean connections, and you lose the ability to return to stock. This harness eliminates 2+ hours of rewiring work and keeps your OEM harness intact and untouched.\u003c\/p\u003e\n\n\u003ch4\u003eWhy SpeedFactory Over a Generic Alternative?\u003c\/h4\u003e\n\u003cp\u003eThe cheap OBD2-to-OBD1 distributor jumpers on Amazon and generic sites use stamped pins that do not fully seat in OE-style housings - leading to intermittent signal loss and ignition timing issues under vibration. SpeedFactory uses OEM-specification pin construction on all connectors, matched to the same terminal standards as your factory Honda harness.

This Rywire budget tucked harness gives you a clean engine bay at a price that won't make you cry. You get the tucked engine side harness plus the EG chassis adapter in the box, so it actually works as a complete plug and play engine swap harness for your 1992-1995 Civic. It fits both B series and D series engines, whether you're doing a B series swap or just refreshing your D series with clean wiring. Rywire builds this in the USA using Mil Spec Teflon coated wire rated to 200°C, which matters when you've got a header cooking the back of your block.\u003c\/p\u003e\n\n  \u003ch4\u003eBudget Doesn't Mean Sketchy\u003c\/h4\u003e\n  \n  \u003cp\u003eThe budget part of this harness is simple, not cheap. You get single black wire color and expandable loom instead of the full mil spec multicolor finish, but you still get brand new connectors, pneumatic crimps, and clear labels on every branch. That combo makes the harness easy to route, easy to troubleshoot, and way cleaner than trying to rework a 30 year old factory harness that's been cooked and hacked up. Rywire pin to pin tests and resistance checks every harness before it ships, which is the difference between a weekend of driving and a week of chasing voltage drop.\u003c\/p\u003e\n\n  \u003ch4\u003eIncludes Engine Harness and Chassis Adapter\u003c\/h4\u003e\n  \n  \u003cp\u003eEvery Rywire B\/D Series harness comes with two pieces: the B1 base engine harness and the corresponding jumper harness for your chassis.

This split design means you can reuse the engine side harness later if you swap it into a different chassis.

This Rywire main relay upgrade harness fixes that permanently. It replaces the failure-prone factory Honda main relay with a standard automotive relay you can grab at any parts store for a few bucks, and it adds a removable kill switch that cuts power at the relay level, so the car won't start unless the switch is plugged in. No cutting or splicing your factory harness, just plug it in and you're done.\u003c\/p\u003e\n\n\u003ch4\u003eWhy The Honda Main Relay Fails\u003c\/h4\u003e\n\n\u003cp\u003eIf you've owned an older Civic, Accord, or Integra, you already know the main relay problem. The factory relay sits in the dash where it gets hot, and the solder joints inside crack over time. When it fails, the fuel pump won't prime and the car won't start, leaving you stranded, and a new factory relay costs far more than it should. This harness swaps the Honda-specific relay for a standard automotive relay. When that relay eventually wears out, you're not waiting on a special-order part or paying dealer markup, you grab a new relay from any parts store and swap it in five minutes.\u003c\/p\u003e\n\n\u003ch4\u003eA Hidden Kill Switch That Actually Works\u003c\/h4\u003e\n\n\u003cp\u003eThe harness includes a removable toggle switch that interrupts power to the main relay. No power to the relay means the fuel pump doesn't run and the car won't start. Someone can turn the key all they want, but without that switch plugged in, the car isn't going anywhere. You unplug the switch and take it with you when you park. It's not a hidden toggle under the dash that a determined thief can find, they'd need the actual switch in hand to start your car, which makes it a simple, effective theft deterrent on a car that predates modern immobilizers.\u003c\/p\u003e\n\n\u003ch4\u003ePlug It In, You're Done\u003c\/h4\u003e\n\n\u003cp\u003eThe harness plugs straight into your factory main relay connector.

The motor's the fun part. The wiring is where a lot of\n  budget swaps turn into a headache, because your B16 or B18 engine harness doesn't just plug into a chassis\n  that came with a D-series from the factory. That's exactly what this Rywire adapter harness fixes. It\n  plugs in between your B-series engine harness and your car's existing wiring, so you get everything\n  talking to each other without cutting, splicing, or depinning connectors one wire at a time. It's the\n  clean, budget-friendly way to handle the electrical side of an EF B-swap and actually get the car running\n  right.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat This Harness Actually Does\u003c\/h4\u003e\n\u003cp\u003e\n  Let's be clear about what you're buying, because adapter harnesses get misunderstood. This isn't a full\n  engine harness, it's the bridge between two harnesses that weren't built to talk to each other. On one\n  side it connects to your B-series engine harness, on the other it plugs into the factory chassis wiring in\n  your EF, and it sorts out the differences in between. So instead of spending a weekend with a wiring\n  diagram, a depin tool, and a roll of tape hoping you didn't mix up a wire, you plug the adapter in and\n  move on. Rywire builds these to keep your car's electrical systems intact and working the way they\n  should, which matters when the alternative is hacking up your original harness and hoping for the best.\n\u003c\/p\u003e\n\n\u003ch4\u003ePick The Right Variant For Your Car (This Part Matters)\u003c\/h4\u003e\n\u003cp\u003e\n  Read this before you order, because this harness comes in three versions and they're not interchangeable.\n  Honda wired these chassis differently depending on the trim and the year, so you've got to match your car\n  to the right one.

Get that right and the harness plugs in like it should. Order\n  the wrong one and it won't line up, so take the extra minute to confirm before you buy.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhy Budget Builders Reach For This\u003c\/h4\u003e\n\u003cp\u003e\n  The EF B-swap is one of the all-time great budget builds, a light little chassis with a screaming VTEC\n  motor in it, and the whole point is doing it without spending Civic-Type-R money. This harness fits right\n  into that philosophy. It saves you the labor and the guesswork of rewiring everything by hand, it keeps\n  your factory wiring usable instead of cutting it up, and it gets you to a running, reliable swap faster.\n  For most people building one of these, that's exactly the trade you want: spend a little on the right\n  adapter, save yourself a whole lot of frustration.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRywire B-swap adapter harness for the 1988-1991 Honda Civic and CRX (EF chassis)\u003c\/li\u003e\n  \u003cli\u003eConnects a B-series engine harness to your factory EF chassis wiring\u003c\/li\u003e\n  \u003cli\u003eNo cutting, splicing, or depinning your original harness required\u003c\/li\u003e\n  \u003cli\u003eChassis- and trim-specific design for a correct fit\u003c\/li\u003e\n  \u003cli\u003eKeeps your factory electrical systems intact\u003c\/li\u003e\n  \u003cli\u003eAvailable in three variants by trim and year (choose the one that matches your car)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1988-1991 Honda Civic\/CRX Si, HF, EX (one variant covers all years)\u003c\/li\u003e\n  \u003cli\u003e1988-1989 Honda Civic\/CRX DX, STD (early variant)\u003c\/li\u003e\n  \u003cli\u003e1990-1991 Honda Civic\/CRX DX, STD (later variant)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Rywire B-series swap adapter harness for the 1988-1991 Honda Civic and CRX (EF chassis).

This Rywire adapter harness takes that headache off the table. It's built specifically for the 96-98 Civic chassis and designed to work with Rywire's B-Series Budget Engine Harness, so instead of splicing, cutting, and praying over your factory wiring, you plug in a purpose-built adapter and move on to the fun part of the build.\u003c\/p\u003e\n\n\u003ch4\u003eWhat An Adapter Harness Actually Does\u003c\/h4\u003e\n\n\u003cp\u003eQuick clarity, because these terms get mixed up constantly and it matters when you're buying. Your engine harness is the one that lives on the motor. This adapter harness is the bridge between that harness and your EK's factory chassis wiring, so an engine your Civic never came with can talk to the car properly. That's it. It's the translator in the middle, and getting it right is the difference between a car that fires up clean and a swap you're chasing gremlins on for months.\u003c\/p\u003e\n\n\u003ch4\u003ePairs With The Rywire Budget B-Series Engine Harness\u003c\/h4\u003e\n\n\u003cp\u003eHere's the thing to sort out before you order, because it trips people up. This adapter is designed to work alongside Rywire's B-Series Budget Engine Harness. It's not a complete standalone wiring solution on its own, it's the chassis-side half of the setup. So make sure you've got the matching engine harness lined up, and you'll have both halves of the wiring covered. Order this by itself expecting it to handle everything and you'll be waiting on parts halfway through the swap.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt For The 96-98 Civic Chassis\u003c\/h4\u003e\n\n\u003cp\u003eThis is made for the EK Civic specifically, covering the CX, DX, EX, GX, HX, and LX trims. That chassis-specific design is the whole value here. It's built around what your car's factory wiring actually looks like, so the connections line up the way they should instead of leaving you to figure out which wire goes where. Rywire builds these with quality materials that hold up in an engine bay, so you're not dealing with brittle insulation or a connection that goes intermittent two summers from now.\u003c\/p\u003e\n\n\u003ch4\u003eWhy It Beats Hacking Up Your Factory Wiring\u003c\/h4\u003e\n\n\u003cp\u003eYou can absolutely wire a B-swap by cutting into your chassis harness and splicing your way through it. Plenty of people have. But every splice is a future failure point, and a car full of them is miserable to diagnose when something acts up at 2am on the way home. An adapter harness keeps your wiring clean and reversible, which matters if you ever go back to stock or sell the car. It also just gets you done faster, and it means the next person who works on the car, possibly you, isn't staring at a rat's nest of electrical tape trying to figure out what happened.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Run This Adapter Harness\u003c\/h4\u003e\n\n\u003cp\u003eThis is for anyone putting a B-series into a 96-98 Civic who'd rather do the wiring properly than improvise it. First swap and the electrical side has you nervous? This takes the scariest part and makes it plug-in. Tenth swap and you just want it clean and done? Same answer.

Whatever trim you started with, the wiring is where a swap either goes smoothly or turns into a weekend you'd rather forget. This Rywire adapter harness is built specifically for the 99-00 EK chassis and pairs with Rywire's B-Series Budget Engine Harness, so you get a purpose-made connection instead of cutting into your car's factory wiring and hoping for the best.\u003c\/p\u003e\n\n\u003ch4\u003eMake Sure You're Buying The Right Year\u003c\/h4\u003e\n\n\u003cp\u003eCheck this before anything else. The EK Civic split mid-generation on its electronics, and the 99-00 cars aren't wired the same as the 96-98 cars. This harness is made for the 1999-2000 chassis. If your Civic is a 96, 97, or 98, you need the version built for those years instead. It's a two-second check on your title or door jamb, and it saves you a return and a stalled build. Get the right year and everything downstream gets easier.\u003c\/p\u003e\n\n\u003ch4\u003eCovers Every 99-00 Trim, Si Included\u003c\/h4\u003e\n\n\u003cp\u003eThis fits the whole 99-00 Civic lineup: CX, DX, EX, GX, HX, LX, Value Package, and the Si. That's worth noting, because plenty of B-swaps start life in a base-model car and plenty of others start in an Si that the owner wants to take further. Either way, this adapter is built around what your chassis wiring actually looks like, so the connections land where they're supposed to instead of leaving you decoding wire colors with a multimeter and a forum thread.\u003c\/p\u003e\n\n\u003ch4\u003eIt's The Chassis Side, Not The Engine Side\u003c\/h4\u003e\n\n\u003cp\u003eWorth being clear about, since harness terminology gets muddy. The engine harness is the one that lives on the motor itself. This piece is the adapter that ties that harness into your Civic's factory chassis wiring, letting an engine your car never came with communicate with it properly. It's designed to work with Rywire's B-Series Budget Engine Harness, so plan on having both parts in hand. This one alone won't complete the swap, it's one half of a two-part solution, and knowing that up front keeps your build moving.\u003c\/p\u003e\n\n\u003ch4\u003eKeep Your Factory Wiring Intact\u003c\/h4\u003e\n\n\u003cp\u003eYou could splice your way through a B-swap. People do it every day. But every cut and every taped joint is a spot that can go intermittent later, usually at the worst possible time, and diagnosing a hacked-up harness is genuinely miserable work. Going the adapter route keeps your chassis wiring original and reversible, which matters if you ever want to return the car to stock or sell it to someone who cares. It's also just faster, and it leaves the car in a state that the next person to work on it, probably you, won't curse at.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Run This Adapter Harness\u003c\/h4\u003e\n\n\u003cp\u003eThis is for anyone dropping a B-series into a 99-00 Civic who wants the electrical side handled properly the first time. Maybe it's a base-model car getting a real engine, maybe it's an Si you're pushing further, maybe you're just tired of hearing swap horror stories about wiring. Grab this along with the matching Rywire budget engine harness, plug things in where they're meant to go, and spend your weekend on the parts of the build you actually enjoy.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 1999-2000 Honda Civic (EK), CX, DX, EX, GX, HX, LX, Value Package, and Si. \u003cstrong\u003eType:\u003c\/strong\u003e B-series adapter harness, chassis side. \u003cstrong\u003eDesigned for use with:\u003c\/strong\u003e Rywire B-Series Budget Engine Harness. \u003cstrong\u003eImportant:\u003c\/strong\u003e not interchangeable with the 1996-1998 Civic version, confirm your year before ordering.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e\u003cspan class=\"tag\"\u003e1999-2000 Honda Civic \u003c\/span\u003e\u003cspan class=\"tag\"\u003e\u003cbr\u003e1999-2000 Honda Civic Si\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\u003cp\u003e(1) Adapter Harness\u003c\/p\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"Rywire","offers":[{"title":"Default Title","offer_id":46132415954978,"sku":"RYW-RY-B-SUB-EK-2B","price":100.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/RYW-RY-B-SUB-EK-2B_ocla.jpg?v=1785439954"},{"product_id":"rywire-b-series-obd1-budget-tucked-engine-harness","title":"Rywire OBD1 B Series Tucked Engine Harness for Civic\/Integra","description":"\u003cul\u003e\n\u003cli\u003eSleek, streamlined engine bay appearance. \u003c\/li\u003e\n\u003cli\u003eCompatible with OBD1 and some OBD2. \u003c\/li\u003e\n\u003cli\u003eHigh-quality, new connectors and materials. \u003c\/li\u003e\n\u003cli\u003eEasy installation with clear labels. \u003c\/li\u003e\n\u003cli\u003eCustom sub-harness for vehicle adaptability. \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- split --\u003e\n\u003cul class=\"tabs\"\u003e\n\u003cli\u003e\u003ca class=\"active\" href=\"#Description\"\u003eDescription\u003c\/a\u003e\u003c\/li\u003e\n \u003cli\u003e\u003ca href=\"#VehicleFitment\"\u003eVehicle Fitment\u003c\/a\u003e\u003c\/li\u003e  \u003cli\u003e\u003ca href=\"#TechnicalData\"\u003eTechnical Data\u003c\/a\u003e\u003c\/li\u003e  \u003cli\u003e\u003ca href=\"#InstallGuide\"\u003eInstall Guide\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e\n\u003cul class=\"tabs-content\"\u003e\n\n\n\u003cli class=\"active\" id=\"Description\"\u003e\n\u003ch3\u003eRywire B-Series OBD1 Budget Tucked Engine Harness - Civic, CRX, Del Sol \u0026amp; Integra\u003c\/h3\u003e\n\n\u003cp\u003eA tucked engine bay is one of those things you can't unsee once you've seen it done right. No wiring draped over the valve cover, no loom sagging across the firewall, just a clean bay where the engine is the only thing you notice. This Rywire budget tucked harness is how you get there on a B-series build without paying Mil-spec money. It's built on the same standards as Rywire's Mil-spec line, the difference being single-color black wire and expandable loom instead of the full-color Mil-spec treatment. Same construction quality, same testing, friendlier price.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt Like The Mil-Spec Harness, Priced Like A Budget One\u003c\/h4\u003e\n\n\u003cp\u003eHere's what you're actually getting, because \"budget\" gets used loosely in this hobby. Every connector and every bit of material is brand new, nothing reused or recycled. Each connector is crimped with pneumatic heads, which is what gives you a true OEM-quality crimp every single time instead of the inconsistent hand-crimp results that cause intermittent gremlins years later. Every heavy interference circuit is properly covered and grounded. And each harness is 100% tested pin to pin and resistance checked before it ships, so you're not the one discovering a bad circuit at 1am with the car half apart. Every connector is also tagged with a white ID label, which makes install dramatically less confusing when you're staring at a pile of plugs.\u003c\/p\u003e\n\n\u003ch4\u003eChange Chassis Without Buying A Whole New Harness\u003c\/h4\u003e\n\n\u003cp\u003eThis is the smartest thing about how Rywire built these. The back-side sub-harness, the part that runs to your interior and shock tower, is specific to your chassis and separates from the main harness. So if you build an EG now and move that same engine into a DC later, you don't buy a whole new loom. You just get the sub-harness for the new chassis and keep everything else. For anyone who builds more than one car, or who's ever sold a shell and kept the drivetrain, that's real money saved down the road. Pick your chassis when you order and Rywire builds the correct sub-harness for it.\u003c\/p\u003e\n\n\u003ch4\u003eRead This Before You Order: ECU Compatibility\u003c\/h4\u003e\n\n\u003cp\u003eThis is the part that catches people, so slow down here.

Same Rywire budget tucked construction that people build clean engine bays around, just terminated for OBD2 distributor, injector, and alternator plugs on the engine side.

Here's How To Tell\u003c\/h4\u003e\n\n\u003cp\u003eGet this right first, because it's the whole decision. The difference between this harness and the OBD1 version isn't your car's year, it's the components bolted to your engine. This OBD2 harness has plugs for OBD2 distributor, injector, and alternator connectors. If your engine is running OBD1 versions of those parts, you want the OBD1 harness instead. Go look at what's actually on your motor rather than assuming based on the chassis, especially if the engine came from another car, which on a swap it usually did. Two minutes under the hood now beats a harness with the wrong plugs on it.\u003c\/p\u003e\n\n\u003ch4\u003eYour ECU Plugs Are Still OBD1, And That's On Purpose\u003c\/h4\u003e\n\n\u003cp\u003eThis surprises people, so let's be clear. Every Rywire engine harness, including this OBD2 one, is built with OBD1 (92-95) computer connectors. That's deliberate, OBD1 ECUs are what most of this crowd tunes on. If you're running an OBD2 computer, a plug adapter handles the connection, but here's the hard limit worth tattooing somewhere: \u003cstrong\u003ethis harness does not support USDM OBD2 computers.\u003c\/strong\u003e Aftermarket computers using OBD2 plugs and non-US OBD2 computers work fine, except for stock H22 and GSR computers. Confirm exactly which ECU you're running before ordering, because this is where builds stall out.\u003c\/p\u003e\n\n\u003ch4\u003eThe Sub-Harness Setup Saves You Money Later\u003c\/h4\u003e\n\n\u003cp\u003eHere's a genuinely clever piece of how these are built. The back-side sub-harness, the section running to your interior and shock tower, is chassis-specific and detaches from the main harness. Move your engine from one car to another down the road and you don't buy a new loom, you just get the sub-harness for the new chassis. Anyone who's swapped shells or sold a project and kept the drivetrain knows how much that's worth. You pick your chassis when you order and Rywire builds the matching sub-harness.\u003c\/p\u003e\n\n\u003ch4\u003eHow These Are Actually Built\u003c\/h4\u003e\n\n\u003cp\u003e\"Budget\" describes the wire color and loom, not the workmanship. Every connector and material is brand new. Each one is crimped with pneumatic heads for a true OEM-grade crimp every time, which is what keeps you from chasing an intermittent connection two years into owning the car. Heavy interference circuits are properly covered and grounded. Every harness gets tested 100% pin to pin and resistance checked before it leaves, and every connector is tagged with a white ID label so the install is obvious instead of a guessing game.\u003c\/p\u003e\n\n\u003ch4\u003eFits The Golden Era Lineup\u003c\/h4\u003e\n\n\u003cp\u003ePick your chassis at checkout and the sub-harness is built to suit:\u003c\/p\u003e\n\n\u003ctable\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth scope=\"col\"\u003eMake\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eModel\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eYears\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003e1988-2000\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCRX\u003c\/td\u003e\n\u003ctd\u003e1988-1991\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eDel Sol\u003c\/td\u003e\n\u003ctd\u003e1993-1997\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eAcura\u003c\/td\u003e\n\u003ctd\u003eIntegra\u003c\/td\u003e\n\u003ctd\u003e1990-2001\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat's On The Harness\u003c\/h4\u003e\n\n\u003cp\u003eEverything a running B-series needs, terminated and labeled:\u003c\/p\u003e\n\n\u003cul\u003e\n    \u003cli\u003eInjectors 1-4 and OBD2 distributor plugs\u003c\/li\u003e\n    \u003cli\u003eAlternator, starter signal, and power distribution cap\u003c\/li\u003e\n    \u003cli\u003eMAP sensor, TPS, IAT (intake manifold style), and knock sensor\u003c\/li\u003e\n    \u003cli\u003ePrimary 4-wire oxygen sensor\u003c\/li\u003e\n    \u003cli\u003eIdle control motor and VTEC solenoid\u003c\/li\u003e\n    \u003cli\u003eEngine coolant temp, H2O sending unit (gauge cluster), and oil pressure sending unit\u003c\/li\u003e\n    \u003cli\u003eElectronic speed sensor, fan switch, and reverse lights\u003c\/li\u003e\n    \u003cli\u003eECU plugs A, B, and D\u003c\/li\u003e\n    \u003cli\u003eGround and two extra wires\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eBefore You Plug It In\u003c\/h4\u003e\n\n\u003cp\u003eHonest note on the policy: these are warrantied and guaranteed to work, but non-refundable once installed.

This is the way out: a new Rywire tucked engine harness built for OBD2 engine components, with the chassis adapter for the early DA's interior and shock tower plugs included in the box. New loom, new connectors, and the OBD0 chassis handled at the plug instead of with splices.\u003c\/p\u003e\n\u003cp\u003ePart number RY-B2-DA-EARLY is the OBD2 version. The engine side gets OBD2 distributor, injector, and alternator plugs, and the ECU side is OBD1, connectors A, B, and D. That combination is the point: a 96-01 donor engine keeps its own electricals, and you tune it the way these cars actually get tuned, on a chipped OBD1 ECU or an S300.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eRywire builds this B-series engine harness (D-series compatible) to the same design as their Mil-Spec line and saves the money on presentation, not construction: single-color black wire in expandable loom instead of the pretty stuff. Every connector and material is new, each one crimped with pneumatic heads for an OEM-grade crimp, and every branch wears a white ID label so the install makes sense while you're doing it. The finished harness is pin-to-pin tested and resistance checked before it ships, and it's made in the USA.\u003c\/p\u003e\n\u003cp\u003eThe design detail we'd point at first is the back side. The section that runs to your interior and shock towers is a separate chassis-specific sub-harness, and on this part number it's the 90-91 Integra USDM adapter. It unplugs from the main loom, so if you ever sell the shell and keep the drivetrain, the engine harness follows the motor and you only buy the sub-harness for the next chassis.\u003c\/p\u003e\n\u003cp\u003eECU support has one hard edge.

Honda changed the chassis-side connectors for 1992, so a 92-93 Integra takes the same engine harness with a different adapter, not this one. And because the engine plugs are OBD2, this version matches an engine wearing OBD2 injectors, alternator, and distributor, which usually means a 96-01 donor B16, B18, or B20, or a D-series converted to match. Rywire doesn't make an OBD2-to-OBD1 alternator adapter, so if your engine still runs OBD1 electricals, order the OBD1 version of this harness for the same chassis instead.\u003c\/p\u003e\n\u003ch3\u003eWhat to Know Before You Buy\u003c\/h3\u003e\n\u003cp\u003ePlan the whole circuit before the box shows up. Rywire's one-piece charge harness for starter and alternator power, injector plug adapters, a ground kit, and their titanium VTEC oil pressure bolt are all options they sell alongside this harness, and none of them come included here. If it were our build, the charge harness goes in the cart with it, because the stock charge wiring is as old as everything else you're replacing.\u003c\/p\u003e\n\u003cp\u003eTwo more things worth knowing before you order. Rywire warranties these and guarantees them to work, but once a Rywire harness is installed it can't be returned, so confirm your ECU, injector plugs, and distributor first. And if this is part of a fresh swap, run the harness while the motor is out of the car. A tuck with the engine in the bay can be done.

On one side you've got budget replacement harnesses with histories nobody can account for. On the other, full motorsports harnesses that cost more than the engine going in. This is the one in between: clean tucked routing, factory Honda wire colors so you can actually trace a circuit, and machine testing on every single harness before it ships.\u003c\/p\u003e\n\n\u003ch4\u003eWhy We Built It\u003c\/h4\u003e\n\n\u003cp\u003eOur first successful product was a K-swap conversion harness, and wiring has been part of what we do ever since. What shaped this design was years of helping customers trace swap problems back to the same handful of causes: wiring errors, and harnesses nobody could vouch for.\u003c\/p\u003e\n\n\u003cp\u003eSo everything here comes from that experience. OEM Honda wire colors so a technician can follow a service manual. Removable injector and VSS adapters so you're never cutting into the main loom. K24 crank and knock sensor connectors in the box. Three spare circuits through C101 for whatever you add later. And a machine test against the production wiring map before it leaves the building.\u003c\/p\u003e\n\n\u003ch4\u003eClean Routing You Can Still Work On\u003c\/h4\u003e\n\n\u003cp\u003eThe branches take a tidier path through the bay and tie down at factory mounting locations, which does two things. It looks right with the hood up, and more importantly it stops the harness moving around, which is what causes rubbing and eventual wear-through.\u003c\/p\u003e\n\n\u003cp\u003eThe wire colors and stripe patterns follow the corresponding Honda circuits. That sounds minor until you're troubleshooting at midnight and can pull up a factory service manual and trace exactly what you're holding. A harness in generic colors leaves you guessing.\u003c\/p\u003e\n\n\u003ch4\u003eChange Connections Without Cutting\u003c\/h4\u003e\n\n\u003cp\u003eThis is the design decision we're proudest of. The injector and VSS connections live on removable adapter harnesses that plug into the main loom rather than being wired into it.\u003c\/p\u003e\n\n\u003cp\u003eIt ships with an injector adapter for 2002-2004 RSX Type-S and K20A2-style injector connectors, the ones people call Honda OBD2 injector clips, plus a VSS adapter for the K20A2 final-drive-driven speed sensor. If your injectors or transmission use different connectors, optional adapters swap right in. \u003cstrong\u003eNo cutting, no depinning, no repinning the main harness.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThat matters over the life of a build, because setups change.

Depin the terminals from the K20 crank and knock sensor connectors, repin them into the included K24 connectors during installation, and you're set.

Running a big pump on the stock wiring gives you a pump that's slow, hot, and starved at the top of the rev range where you need it. Radium's 17-0031 is everything to wire one pump properly, with a sealed 40 amp relay, a sealed fuse holder, 10 gauge wire, and the connectors, in a single kit with a wiring diagram.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eThe kit builds a dedicated power circuit for one pump: battery to a 20 amp mini fuse, fuse to a 12 volt 40 amp SPDT relay, relay to the pump on 10 AWG, with the factory pump signal used only to trigger the relay. The relay and fuse holder are weatherproof with mounting tabs, so they can live in a trunk or under the car near a surge tank. The wire is 10 AWG TXL, the thin-wall aircraft-grade insulation that shrugs off fuel and heat and takes up half the space of GPT wire. Connections are Raychem solder-sleeve butt splices that shrink and solder in one step, plus a Posi-Tap for the trigger, four 6mm ring terminals and one 5mm, which is what you need to land on a Bosch 044 or a bulkhead stud.

The trigger can be a switched 12 volt or a ground, as long as the other side of the relay coil goes to the opposite; the factory pump feed is the usual trigger, tapped with the Posi-Tap. Ten gauge is right for a 450 or an 044; if you're running a brushless pump that pulls more than 20 amps, you need a bigger fuse and wire than this kit. Route the 10 AWG away from the exhaust and through grommets, and put the fuse as close to the battery as you can.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003ctd\u003eAny single 12V fuel pump up to the 20A fuse; in-tank, surge tank, or external\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eNot vehicle-specific.

The 88-91 CRX HF and Si came with non-VTEC engines, so the factory OBD0 harness is missing the circuits a B16A needs to run VTEC and its extra sensors. This sub harness fills that gap, adding the wires for your VTEC solenoid, VTEC oil pressure switch, secondary oxygen sensor, and knock sensor so the B16A functions the way it should.\u003c\/p\u003e\n\n\u003ch4\u003eWhy You Need It\u003c\/h4\u003e\n\n\u003cp\u003eA B16A is a VTEC engine, and VTEC doesn't just bolt on electrically. The engine needs the ECU to control the VTEC solenoid, read the VTEC oil pressure switch to confirm it actually engaged, and monitor the knock sensor and secondary O2 sensor. The factory HF\/Si OBD0 wiring doesn't run any of those, so without this sub harness you'd be splicing in circuits by hand. This kit adds them cleanly instead, so the swap keeps full VTEC function and proper sensor feedback.\u003c\/p\u003e\n\n\u003ch4\u003eWhat It Adds\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eVTEC solenoid wiring\u003c\/li\u003e\n  \u003cli\u003eVTEC oil pressure switch wiring\u003c\/li\u003e\n  \u003cli\u003eSecondary (2nd) oxygen sensor wiring\u003c\/li\u003e\n  \u003cli\u003eKnock sensor wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003eBuilt for the 1988-1991 Honda CRX (HF\/Si) with a B16A swap, OBD0.
