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, 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!

Fits 2001 Bayliner
This product was definitely different than the original I have a 2001 Bayliner with a 3.0 MerCruiser and an alpha one second GEN drive The kit worked but the bottom gasket had a weird cut different than the original I added a gasket maker just in case (Yamaha Lube) Brand! All in all kit was fine, One thing to note is the directions that come with the kit at least for my version we’re not for the same alpha one second GEN 4 stroke kit that I got they were for a two-stroke in the pictures didn’t look the same as the parts that I had got which is fine but it’s miss leading when you send a 4 stroke kit but 2 stroke 90hp to 200hp alpha one directions! If it craps out this review will change

Super great product. Has the power and functionality to get you repairing fast! Fully recommend this and it has worked great since I've owned it. Still going strong in the durability and design looks like it will keep it going strong for many years. Highly highly recommend buying this. Will work in Kuwait, Iraq, UAE, and Saudi. Good for Camps around the CENTCOM area!

Nice flexible silicone wire
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I purchased to replace the main power cable for an Ender 3 3D printer. The original cables were the same type but had a cheap connector Midway through to allow the power supply to be removed if needed. THOSE NYLON connectors overheated, smelled and turned black. The BNTECHGO 14 Gauge Silicone Wire were a perfect replacement. No more connector and no more heat issues.
