Our K-series swap conversion harnesses are built around one simple goal: to make engine swaps reliable, straightforward, and as close to OEM quality as possible. We were the first company to develop and offer K-swap conversion harnesses back in 2003, helping establish the standard that countless Honda enthusiasts still rely on today. Every harness is assembled in the USA using OEM-sourced connectors, terminals, seals, and wiring components to ensure proper fitment, long-term durability, and dependable electrical performance. Rather than adapting questionable used parts or low-quality aftermarket connectors, we build each harness with the same attention to detail that modern factory wiring systems demand.
Over the years, we've expanded our lineup to support some of the most popular Honda and Acura chassis, including the EF Civic, EG Civic, EK Civic, DC2 Integra, and EM2 Civic. For dedicated motorsports and custom applications, we also offer a universal K-swap harness that provides the flexibility race car builders need without sacrificing quality or reliability. Whether you're completing your first K-series conversion or building a professional-level track car, our conversion harnesses eliminate wiring guesswork and provide a proven solution backed by more than two decades of K-swap experience.
