Hybrid Racing K-Swap Electronics Package for 92-95 Civic/Del Sol/94-01 Integra

Hybrid Racing K-Swap Electronics Package - EG Civic, Del Sol & DC Integra

Wiring is where K-swaps stall out. Not because it's impossible, but because sourcing the right harnesses and grounds from multiple places is tedious and easy to get wrong. This package puts the major wiring components in one box, and every piece is chosen to work with the others. It covers the three chassis most K-swaps end up in.

Photo Note

The engine harness shown in the product photos is not the current Hybrid Racing harness. This package now ships with our own Tucked K-Swap Engine Harness. Updated photography is coming, but what you'll receive is the Hybrid Racing harness described below.

What's In The Box

Hybrid Racing Tucked K-Swap Engine Harness. Built around 02-04 RSX and K20A2 wiring with clean tucked routing and factory Honda wire colors.

Hybrid Racing K-Swap Conversion Harness. Connects your engine harness and ECU to the chassis wiring and instrument cluster.

Hybrid Racing K-Swap Ground Kit. The unglamorous piece that prevents a long list of electrical problems.

The Engine Harness

Our Tucked K-Swap Engine Harness is built around 2002-2004 RSX and K20A2 wiring, and it sits between a budget replacement and a full motorsports harness.

It uses AVSS thin-wall automotive wire built to JASO D611, with OEM Honda color and stripe patterns throughout. That detail matters more than it sounds. When you're troubleshooting at midnight, being able to pull up a factory service manual and trace exactly what you're holding is worth a great deal over a harness in generic colors.

The injector and VSS connections live on removable adapter harnesses, so if your injectors or transmission change later, you swap an adapter rather than cutting into the main loom. K24 crank and knock sensor connectors come in the box, and there are three spare circuits through unused C101 positions for whatever you add down the road.

Every harness is machine tested against the production pin-to-pin wiring map for incorrect connections, opens, and shorts before it ships.

The Conversion Harness Is Plug And Play

This is the piece that makes the swap manageable rather than a wiring project.

It connects your engine harness and ECU to the chassis wiring, and it retains full functionality of the factory instrument cluster. Built with connectors, terminals, and wire from the same supplier Honda uses, ordered in bulk from Japan.

There's a reason it's the most widely used conversion harness on the market. It installs intuitively and it makes a K-series feel like something Honda put in the car, rather than something obviously grafted in.

The provision for a wideband O2 sensor is built in, so when you fit one it plugs straight in rather than needing wiring work.

No core exchange required. You get a brand new harness rather than sending in parts of yours and waiting.

Don't Overlook The Ground Kit

Grounds are the least interesting part of an electrical system and among the most important. Without good ground connections there's nowhere for current to go, and the symptoms are maddening: faulty sensor readings, electronics failing early, and problems that come and go with no obvious cause.

On a swapped car that's worse, because you've already introduced enough variables without wondering whether a ground is at fault. The kit gives you proper length and proper connections rather than cutting and splicing to make something reach.

What You'll Still Need

Worth being clear so nothing stops you mid-build.

This package covers the wiring. It does not include an ECU or a wideband O2 sensor, so plan on sourcing both. The harness is wideband compatible with the provision already wired in, you just supply the sensor.

You'll also need a K-series ECU matching your engine. Worth resolving early, since a factory ECU in a swapped chassis has to get past the immobilizer before the engine will run.

Fitment

1992-1995 Honda Civic (EG)
1993-1997 Honda Del Sol
1994-2001 Acura Integra (DC)

For K20A and K20A2 engines with a matching ECU. Other K-series engines may work but could require changing sensors or sensor connectors.

Who Should Grab This

This is for the builder K-swapping an EG, Del Sol, or DC who wants the wiring handled properly rather than assembled from separate orders and hoping the pieces cooperate. These are the chassis K-swaps were built around, and everything here is chosen to work together, which removes the compatibility guesswork that makes swap wiring miserable. Sort your ECU and wideband, get the package, and get the engine running.

Fits: 1992-1995 Honda Civic (EG), 1993-1997 Honda Del Sol, and 1994-2001 Acura Integra (DC) with K20A or K20A2. Includes: Hybrid Racing Tucked K-Swap Engine Harness, K-Swap Conversion Harness, and K-Swap Ground Kit. Not included: ECU and wideband O2 sensor, though the harness is wideband compatible. Note: no core exchange required. Product photos do not yet show the current Hybrid Racing engine harness.
