    Will It Fit Your Vehicle?


    This harness works with all USDM / JDM 02-04 wiring harnesses including, K20A, K20A2, K20A3. This harness is wired to use the factory wideband O2 sensor so European customers using the UKDM K20A/K20A2 wiring harness will need to convert the harness to use the narrowband type sensor.

    This harness does NOT work with any 05-06 OR K24 engine wiring harnesses.


    • NO CORE required.
    • Brand new connectors and pins sourced from the same company Honda uses.
    • Free phone and email tech support.
    • 1000's of customers can't be wrong.
    • For 2002-2004 engine wiring harnesses only.

    What makes Hybrid Racing's Harness the best on the market?

    With over ten years of K-Series swap wiring experience, the Hybrid Racing Conversion Harness is the most widely used and reliable conversion harness on the market. Over the years we have sold and installed thousands of these into all types of cars all over the world! This harness interfaces with the factory dash harness, your OEM K-Series engine harness and your K-Series ECU to greatly simplify the swap wiring.

    What's new about the Version 4 Hybrid Racing Harness?

    The new Hybrid Racing Conversion harness incorporates updated wiring to make for an even easier install, updated install guide that includes more pictures and less text and the integration of the primary oxygen sensor connector. Every harness is machine made and human checked so they are issue free.

    What type of connectors and pins do you use?

    When we construct a Hybrid Racing harness we utilize brand new connectors, terminals and wire sourced from the same company that Honda utilizes for their connectors.

    These connectors are ordered in bulk from Japan and ensure that you get all new parts. In addition, all new connectors decrease the chance for errors in the harness as we do not solder any of the joints. The Hybrid Racing Conversion Harness allows for full functionality of the factory gauge cluster and comes with full replacement warranty.

    Other companies will have you send in parts of your stock harness wasting time and money in shipping. The Hybrid Racing Conversion Harnesses are in stock and ready to ship. You do not have to send us a core and they are available for overnight shipment.

    What if I have questions or problems?

    To ensure a trouble-free install all of the wires are labeled and neatly packaged. The most valuable thing you get when you purchase a Hybrid Racing harness is full tech support. This tech support extends beyond your harness and includes help with anything associate with your swap. If you have any problems at all with the swap just give us a call and a tech will get you the information you need. It’s like having a buddy down the street who has already done hundreds of K swaps!
