Hybrid Racing Universal K Swap Conversion Harness

Hybrid Racing Universal K-Swap Conversion Harness

The Hybrid Racing Universal K-Swap Conversion Harness lets you install a K-series engine into virtually any chassis or custom build. From sandrails and RWD K-swaps to VW Beetles, Mini Coopers, Toyota MR2s, Lotus Elises, and full tube-frame race cars, this harness is built to support your project. It's also the answer for older Honda chassis, Preludes, DA Integras, and Accords where a standard plug-and-play harness isn't available.

With over ten years of K-series swap wiring experience behind it, this conversion harness is widely used and highly reliable. It interfaces with your factory dash harness, the OEM K-series engine harness, and the K-series ECU, so you get a simple plug-and-play setup while keeping full functionality of the OEM systems.
