    What engine harness does the Hybrid Racing conversion harness work with?

    • This harness works with all USDM / JDM 02-04 wiring harnesses, including, K20A, K20A2, and 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 and ECU.
    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. Every harness is machine-made and human checked, so they are issue-free.

    What if I have questions or problems?

    To ensure a trouble-free install, all 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 associated 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!
