KTH-204-RCE Applications: Custom setups - Race Applications. We stepped into the wiring market for a reason. To release what we feel is the highest quality and easiest to install conversion harness available. We’ve used several of our competitor’s harnesses and in short, we felt the need to make several improvements based on the flaws we encountered. Just like every other K-Tuned product, they don’t leave our hands unless we feel that it is a top quality part that we would use on our own personal cars. A K-swap conversion harness is a must-have part for any K-series engine swap. The harness is designed for custom applications. The harness includes plugs needed to connect to the engine harness, necessary relays, and labeled flying leads. This saves a lot of time sourcing plugs and figuring out wiring.
