Who should purchase the Universal Harness?

The Hybrid Racing Universal K-Series Swap Conversion Wiring Harness is designed for those people who have decided to install a K-Series engine into a non-honda chassis or a chassis where a standard plug and play conversion harness is not available. (such as Preludes, DA Integras, Accords, and older Honda chassis)

This harness has also been used in custom open wheel cars such as the Ariel Atom, RCR Superlite Roadster, Sandrails, and 3 wheeled Trikes. It has also been used on Mini Coopers, Toyota MR-2s, Lotus Elises as well as full blown tubed frame race cars.

If your engine of choice is the K-Series motor and plan to use the OEM K-Series ECU than we can help you get it started.

What is included with the race harness?

The race harness includes a fuel pump relay, a main relay and a primary oxygen sensor relay. The harness comes wired with the provisions for the OEM K-Series 02-04 Wideband o2 sensor and an OBD2 port. This harness has outputs including, tachometer, speedometer, low oil pressure warning, malfunction indicator, fan control, fuel pump control and for the starter relay. You will need to supply the harness with a constant 12v and switch 12v source.

With over ten years of K-Series swap wiring experience, the Hybrid Racing Conversion Harness is the most widely used and reliable K-Swap conversion harness on the market. This conversion harnesses powers thousands of K-Swaps all over the world!

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, 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!

Stylish, packable warmth layer I'm using for travel the fits and looks great!
Size: Large, Color: Gray, Size: Large, Color: Gray
I like the COOFANDY brand a lot for good looking clothes, that fit me correctly (Large size, for me 180lbs 6'0", athletic build), all at a reasonable price. This Jacket fits me great and looks great, and it's stylish enough that I'll feel comfortable going to museums and restaraunts, etc while we're away in Europe this fall. I bought the gray which looked correct vs images on the web, and a good color in my opinion. My pictures were done in different lighting because of needing to be in front of the mirror, but color is accurate on web. I like having the hood, which will be good for outdoor travel / walking in sometimes rainy weather, and hood looks good down (not too bulky). Zippers seem good quality, and I like zippered pockets, plus there's internal pockets (not zippered) if you desire, and an included stash back for compact packing into my day pack. Sleeve cuffs and right size and nice. Note, that there is no bottom waistline drawstring adjustment, but I don't need such because it fits me great and I wanted something more city and less outdoorsy. Really like this jacket for my need, outer layer for city type travel while staying warm and looking good.
