Hybrid Racing K-Swap Conversion Harness for EG Civic/DC Integra

Hybrid Racing K-Swap Conversion Harness - 92-95 Civic (EG), 93-97 Del Sol, 94-01 Integra (DC2/DC4)

If you're K-swapping an EG Civic, a Del Sol, or a DC Integra, the wiring is the part that scares people off, and this is what makes it painless. 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.

What A Conversion Harness Actually Does

Quick 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.

Why This Harness Over The Others

Here'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.

Built Right, So It Lasts

A 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.

Compatibility

This conversion harness fits the 1992-1995 Honda Civic (EG), 1993-1997 Honda Del Sol, and 1994-2001 Acura Integra (DC2 and DC4). Here's exactly what it works with, and what it doesn't:

• Works with USDM and JDM 02-04 K-series engine harnesses, including K20A, K20A2, and K20A3
• Uses the factory wideband O2 sensor. European customers running UKDM harnesses may need to convert to narrowband
• Does NOT work with 05-06 or K24 engine harnesses and ECUs
• Not compatible with some European-market 92-95 Civics equipped with a carburetor

If you're running an 05-06 or K24 engine harness and ECU, this isn't your harness, so check your engine harness year before ordering.

What Makes It Worth It

• Fits EG Civic, Del Sol, and DC2/DC4 Integra K-swaps
• True plug-and-play into the factory dash harness, K-series engine harness, and ECU
• Retains full factory gauge cluster functionality
• Brand-new, Honda-quality connectors, terminals, and wire
• Machine-made and human-checked, with no soldered joints
• Every wire clearly labeled for a clean install
• Ships fully assembled, no core harness to send in
• Full replacement warranty and expert tech support included

Who This Is For

This is for anyone dropping a K-series into an EG Civic, a Del Sol, or a DC Integra who wants the wiring done right the first time. Whether it's your first swap and the harness has you nervous, or your tenth and you just want a clean, reliable, no-core conversion harness that shows up ready to plug in, this is the one thousands of builders keep coming back to. Order it, plug it in, and get back to the fun part of the build.
