    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!

The worst banking experience
Stay away from this card if you want to keep your sanity, they had a welcome offer of $750 that they refused to honor, if you call customer service you will be on hold for 2 hours just for them to transfer the call to someone that doesn't know what they're doing. they still ask you to send them documents by mail or fax to prove you're not lying to them. I closed their card less than a month after opening it, the worst banking experience of my life.

Not good if you need Whole Foods gift cards
If you want to buy Whole Foods gift cards (which is why I got it) it flags it for fraud and doesnt let you. I was told you can spend at Whole Foods but not buy WF gift cards, even though it is a Prime Credit Card. Also if you buy WF gift cards online, you dont get the rewards since its from a gift card company and not Whole Foods.
