    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!

Quality could be better
Really cool product but quality is not the greatest. I have tried three times and my GSD destroys them within a hour. Feel the stitches are too light and easy to rip

Dogs love this toy!
I've purchased a couple of these and the dogs love them. Good for puppy teeth and adult chewers. Can be torn up but last for dogs that like to chew.

Beware not as described!
I have ordered these multiple times in the past because our pup loves them. However, what I received this time is much smaller than before and does not match the dimensions on the site (6 in versus the expected 9). Very disappointed since I ordered two and these are not cheap toys.

My Bulldog’s Very Favorite
These are the best toys! My bulldogs love all the different shapes and sizes and I buy multiple per year. I feel comfortable with the safety of this material, even though they start wearing it down very quickly.
