    The K-Swap harness interfaces with your factory dash harness, your OEM K-Series engine harness and your K-Series ECU allowing for a simple plug-and-play K-Swap.

    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!

Lil boy's favorite ball
Style: Recharges, Size: Medium
The squeak gets my little boy every time. The glow factor is under par. I mainly get it because he also enjoys the brighter colors. All of the others be trying to get his ball. Good product just wish it would glow better because our park times are right around sunset.

The glow doesn’t last long, not super bright.
Style: Recharges, Size: Medium
I charge my glow in the dark balls with a black light flashlight, this one was not very bright, and it did not hold the charge very long. Also, with it being green, it was hard for my dog to find in the grass.
