You need a proper ground kit. The Hybrid Racing K swap ground kit eliminates the guesswork that comes with grounding a swapped engine. Factory harnesses aren't long enough for swapped applications, and bad grounds cause starting issues, ECU errors, rough idle, and misfires. This kit gives you the correct length wires and all the hardware to establish solid grounds without cutting, splicing, or making up your own lengths. Just bolt it in and move on.\u003c\/p\u003e\n\n  \u003ch4\u003eWhy Swaps Need a Ground Kit\u003c\/h4\u003e\n  \n  \u003cp\u003eK swaps move the engine forward and change the grounding points compared to where a B or D series sat. Factory ground wires aren't the right length anymore, and most people end up splicing extensions or running undersized wire to make up the difference. Poor grounds cause all kinds of electrical problems that are annoying to diagnose. The starter cranks slow, the ECU throws random codes, the engine runs rough, or accessories don't work right. This kit fixes all of that by giving you proper length grounds with the correct gauge wire and clean connections.\u003c\/p\u003e\n\n  \u003ch4\u003eDesigned for EG, EK, Del Sol, and DC2 Chassis\u003c\/h4\u003e\n  \n  \u003cp\u003eThe kit's designed specifically for 1992-2000 Civic (EG\/EK), 1993-1997 Del Sol, and 1994-2001 Integra (DC2) K swaps.

The Rywire 6-toggle switch panel gives you a clean way to control your fuel pump, fans, ignition, and starter without a mess of loose switches and relays. You're getting six water-resistant rocker switches mounted in a CNC-machined aluminum panel that's 7.75\" wide and 2.5\" tall. The panel's wired with Tefzel wire and Raychem DR25 heat shrink, and it terminates in a 12-pin DTM connector so you can unplug it and pull it out for maintenance. If you're building a track car, drag car, or street car with a standalone ECU and you need clean switch control, this is what you need.\u003c\/p\u003e\n\n\u003ch4\u003eHere's What You're Getting\u003c\/h4\u003e\n\n\u003cp\u003eYou're getting one master ignition switch (red), one momentary starter switch, and four on\/off toggle switches. The master ignition switch is high-side activation, which means it supplies 12V power when it's on. The momentary starter switch is low-side activation, which means it grounds the circuit when you push it. Three of the four on\/off switches are low-side activation and one's high-side activation. That mix matters because you can use the low-side switches to trigger relays for fuel pumps, fans, or water pumps, and you can use the high-side switches for direct 12V control of accessories.\u003c\/p\u003e\n\n\u003ch4\u003eHigh-Side vs Low-Side Switching\u003c\/h4\u003e\n\n\u003cp\u003eHigh-side switches supply 12V power when they're turned on. You're running power directly to whatever device you're controlling. Low-side switches ground the circuit when they're turned on. They're used to trigger relays or send a ground signal to an ECU or a relay. Most fuel pumps, fans, and water pumps are controlled with relays, so you need low-side switches to trigger those relays. The Rywire panel gives you both high-side and low-side switches so you can wire whatever you need without adding extra relays or modules.\u003c\/p\u003e\n\n\u003ch4\u003eWater-Resistant Rocker Switches\u003c\/h4\u003e\n\n\u003cp\u003eThe switches are water-resistant rocker switches. They're sealed so they won't corrode or fail if they get splashed with water or fluids. If you're running this panel in a gutted track car or a car that sees rain, the switches aren't going to fail on you.\u003c\/p\u003e\n\n\u003ch4\u003eTefzel Wire and Raychem Heat Shrink\u003c\/h4\u003e\n\n\u003cp\u003eRywire wires the panel with Tefzel wire and Raychem DR25 heat shrink. Tefzel's a high-temp, abrasion-resistant wire that's used in aerospace and motorsport wiring. It doesn't melt or crack like cheap PVC wire does. Raychem DR25 heat shrink is dual-wall heat shrink with adhesive inside. It seals connections way better than cheap heat shrink. You're getting professional-grade wiring, not budget eBay harness garbage.\u003c\/p\u003e\n\n\u003ch4\u003e12-Pin DTM Connector\u003c\/h4\u003e\n\n\u003cp\u003eThe panel terminates in a 12-pin DTM connector. That means you can unplug the entire panel and pull it out for maintenance or troubleshooting. You're not soldering and unsoldering wires every time you need to work on the panel. Unplug it, take it to the bench, fix it, plug it back in. DTM connectors are waterproof and they lock in place, so you're not dealing with loose connections.\u003c\/p\u003e\n\n\u003ch4\u003eIncludes Label Decals\u003c\/h4\u003e\n\n\u003cp\u003eRywire includes a decal sheet so you can label each switch.

That matters when you are actually trying to read it in a quick pull or a long hill climb, not when you are staring at it in the garage. It also stays easy to mount in common pods since it keeps the normal 52mm footprint. Depth is where this AEM wideband gauge gets practical, it measures under one inch overall, and the cup depth is only 0.200 inches, so you can fit it in spots that usually force you into a clunky pod setup.\u003c\/p\u003e\n\u003cp\u003eOn the face, you get buttons that let you set it up the way you actually tune. You can run it as an AEM Lambda gauge, a traditional AFR readout, or O2 percent, and you can change the center display between three or four digits depending on how much detail you want while driving. You can also do a free air calibration if you want as the sensor ages, and if you are stacking multiple controllers you can change the CAN message ID so everything plays nice together. Out of the box you get a black bezel and a black dual faceplate that covers air fuel and Lambda. If you want the cleaner white look, AEM sells an AEM X-Series accessory face and bezel separately, PN 30-0300-ACC, which is the AFR gauge silver bezel setup with the white dual faceplate. If you are specifically after an AEM white face gauge, this is how you do it. It is a customizable AFR gauge, but it is still a gauge first, you will spend a few minutes in the menus up front to get it exactly how you want.\u003c\/p\u003e\n\u003cp\u003eIt has auto dimming so it does not burn your eyes at night, and it uses locking connectors, which sounds boring until you have chased an intermittent wideband signal for an hour. AEM also uses a single board design here to improve durability. We run these exact AEM UEGO gauge setups on our own cars because they are readable, consistent, and they log cleanly.\u003c\/p\u003e\n\u003cp\u003eFor outputs, this AEM wideband kit gives you 0 to 5V and an RS232 serial port for feedback control and datalogging, plus AEMnet CANbus for logging and sharing data. With AEMnet you can daisy chain multiple X-Series wideband controllers, up to 16 cylinders, so you can log per bank or per cylinder on more serious builds. It supports up to 16V system voltage, works on EFI or carb setups, and it is happy on a dyno. Fuel support covers the real world mix, gasoline, ethanol, methanol, diesel, propane, and CNG. If you want one X-Series AFR gauge or you are building a full X-Series gauge kit around CAN, this one does both without drama.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n    Universal \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n52mm Gauge Diameter\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\nReplace the existing bezel and faceplate on your X-Series Wideband UEGO AFR Gauge with the components from this kit.

Bad grounds are usually the culprit. The Rywire universal ground kit gives you a 20-inch 4-gauge battery ground cable and three 14-inch 8-gauge ground wires for your transmission and engine grounds. The factory ground wires corrode over time, develop high resistance, and cause voltage drop that messes with your sensors, charging system, and starter. Fresh ground wires fix that.

Think of it as a Link CAN wideband controller that sends your Link ECU air fuel ratio and lambda info digitally over CAN, instead of hoping an analog voltage stays clean. If you tune your own car, or you pay a tuner and actually want to verify what the engine sees, this ECU monitoring module Link setup becomes one of those parts you stop thinking about because it just works. We run these exact modules on our own cars because guessing at AFR is how engines learn expensive lessons.\n\u003c\/p\u003e\n\n\u003cp\u003e\nHere’s the big difference. This digital wideband with CAN uses a Bosch LSU 4.9 wideband sensor, then pushes the data over the CAN bus wideband module connection. That means you avoid the usual analog headaches, voltage drift, electrical noise, and chasing phantom lean spikes. Link calls it a digital lambda module Link for a reason, it stays digital all the way to the ECU. You also skip free air calibration because the module uses the OEM sensor trim resistor for automatic calibration. In the real world, that means your wideband O2 module Link data stays consistent when the car gets heat soaked on track, when the fans kick on, or when the ignition system tries to spray noise into everything.\n\u003c\/p\u003e\n\n\u003cp\u003e\nFor Link CAN lambda integration, you wire it into your existing CAN network and set it up in PCLink. It plays nice as a Link lambda controller for monitoring or closed loop fueling, and it’s a solid race car lambda module option if you want repeatable data lap after lap. Link ECU supports stacking up to eight units on one bus, handy if you’re doing staged banks, multiple engines, or you just like logging everything. It also works as a Link G4+ compatible module, and it’ll talk to other ECUs that support configurable CAN. If your car already has CAN, adding a wideband sensor with CAN usually feels easier than running analog back to the ECU and hoping your grounding is perfect.\n\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLink ECU CAN Lambda, a Link CAN wideband controller that runs a Bosch LSU 4.9 wideband sensor\u003c\/li\u003e\n  \u003cli\u003eCAN bus wideband module comms for clean data to the ECU, not a noisy analog voltage\u003c\/li\u003e\n  \u003cli\u003eNo free air calibration needed, automatic calibration via OEM sensor trim resistor\u003c\/li\u003e\n  \u003cli\u003eWorks as a wideband O2 module Link for monitoring and closed loop lambda control\u003c\/li\u003e\n  \u003cli\u003eLink CAN lambda integration through PCLink configuration\u003c\/li\u003e\n  \u003cli\u003eCompatible with Link G4+, G4X, plus other aftermarket ECUs with configurable CAN\u003c\/li\u003e\n  \u003cli\u003eHandles wide temperature swings without the usual wideband drama\u003c\/li\u003e\n  \u003cli\u003eSupports up to eight modules on a single CAN bus\u003c\/li\u003e\n  \u003cli\u003eConfigurable CAN bit rates including 1Mb\/s and 500kb\/s\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSensor Type: Bosch LSU 4.9 (aftermarket use only), Bosch LSU 4.9 for Link\u003c\/li\u003e\n  \u003cli\u003eLambda Measurement Range: 0.67 to 10.0 lambda\u003c\/li\u003e\n  \u003cli\u003eCAN Communication: 1Mb\/s, 500kb\/s, 250kb\/s, 125kb\/s\u003c\/li\u003e\n  \u003cli\u003eInput Voltage: Controller 7.5 to 20V, Sensor 10.8 to 16.5V\u003c\/li\u003e\n  \u003cli\u003eOperating Temperature: -20°C to 100°C\u003c\/li\u003e\n  \u003cli\u003eEnclosure Dimensions: 60 x 26 x 15 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eBox Contents\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLink CAN Lambda Module, SKU: LNK-125-1000\u003c\/li\u003e\n  \u003cli\u003eBosch LSU 4.9 Wideband O2 Sensor\u003c\/li\u003e\n  \u003cli\u003eDeutsch 4 Way Connector Kit\u003c\/li\u003e\n  \u003cli\u003eO2 Bung and Plug\u003c\/li\u003e\n  \u003cli\u003eQuick Start Guide\u003c\/li\u003e\n  \u003cli\u003eLink Stickers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n Universal \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) CAN Lambda Module\u003cdiv\u003e(1) O2 Sensor\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Link ECU","offers":[{"title":"Default Title","offer_id":44760035360802,"sku":"LNK-125-1000","price":395.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/LNK-125-1000_j020.jpg?v=1768931308"},{"product_id":"rywire-main-relay-kill-switch-harness-obd0-obd1-obd2","title":"Rywire Main Relay Kill Switch Harness","description":"\u003cul\u003e\n\u003cli\u003ePlug and Play Installation \u003c\/li\u003e\n\u003cli\u003eCompatibility with OBD0 and OBD1\/2 Vehicles \u003c\/li\u003e\n\u003cli\u003eUpgraded Automotive Relay \u003c\/li\u003e\n\u003cli\u003eIntegrated Security Vehicle Kill Switch \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=\"#Included\"\u003eIncluded\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 Main Relay Kill Switch \u0026amp; Upgrade Harness - OBD0 \/ OBD1-OBD2\u003c\/h3\u003e\n\n\u003cp\u003eGot an older Honda or Acura that won't start because the main relay's dead again? The Rywire main relay upgrade harness fixes that problem permanently. It replaces the failure-prone factory Honda relay with a standard automotive relay you can pick up at any parts store for a few bucks. The harness also includes a removable kill switch that cuts power at the relay level, so your 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 Factory Relay Fails\u003c\/h4\u003e\n\n\u003cp\u003eIf you've owned an older Honda, you already know about 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, your fuel pump won't prime and the car won't start. You're stranded until you replace it, and a new factory relay costs way more than it should. The Rywire harness swaps the Honda-specific relay for a standard automotive relay. When that relay eventually fails, you're not waiting for a special order part or paying dealer markup. You just grab a new relay from any parts store and swap it in five minutes.\u003c\/p\u003e\n\n\u003ch4\u003eKill 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, your car's not going anywhere. You just unplug the switch and take it with you when you park. It's not some hidden toggle under the dash that someone can find if they're determined. They'd need the actual switch to start your car.\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. Unplug the old relay, plug in the Rywire harness, mount the new relay somewhere convenient, and route the kill switch wherever you want it. You're not cutting wires or soldering anything. The whole install's reversible if you ever need to go back to stock.\u003c\/p\u003e\n\n\u003ch4\u003eOBD0 or OBD1\/OBD2?\u003c\/h4\u003e\n\n\u003cp\u003eYou need to order the right version for your chassis.
