    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, 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 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!

Genuine leather upper and well made
Size: 10, Color: Sunlight
These shoes are well made and I love the way they look. They look great with jeans or dresses. I usually wear a 9 1/2 or 10 depending on the brand. These are a size 10 and fit. Hopefully after a breaking in period the opening at the toes will loosen up. Also, when walking they make a slap slap sound. Again, hoping after they break in that won't be the case. I got a great deal and poof a couple of days later there was a slightly better deal. I wasn't sure I'd like the color but it's actually really nice. The upper is genuine leather and they are well made.

Beautiful shoe
Size: 7, Color: Smoke Grey
This shoe is fairly narrow, which works fine for my narrow feet. Comfortable. Light. Nice color will match with lots of colors. Fairly comfortable but the skinny part by the toe I see how this would give anyone with a medium side foot blisters. It’s fine on me.

Runs small
Size: 8.5, Color: Sandstorm
This shoe is super cute and comfy. I usually wear an 8 or an 8½. I ordered the 8½, but it was too small, so I had to send it back. I reordered a 9, and it fit perfectly.
