Rywire Honda F/H-Series Mil-Spec Engine Harness w/Chassis Specific Adapter

If you're swapping an F-series or H-series engine into your EF chassis Honda, getting the wiring sorted is a critical step. This Rywire Mil-Spec engine harness is built to make that transition as smooth as possible, ensuring all your engine's sensors and components communicate correctly with the chassis. It's designed to integrate seamlessly, so you can focus on the rest of your build.

Rywire uses Mil-Spec connectors and wire throughout this harness, which means it's built to withstand the rigors of a performance application. The wire itself is high-temperature resistant and oil-resistant, so it can handle the heat and fluids found in the engine bay. The harness includes a chassis-specific adapter, meaning it's tailored to plug directly into your EF chassis's factory wiring points where possible, simplifying the installation process significantly. This attention to detail helps prevent common wiring headaches and ensures a clean, reliable setup for your engine swap.

This harness is designed to connect your F or H-series engine's ECU to the necessary sensors and actuators, including fuel injectors, ignition coils, oil pressure, coolant temperature, and more. It's a well-built solution for anyone serious about completing a clean and functional engine swap in their EF chassis. While this harness handles the engine's needs, always refer to your specific chassis and ECU diagrams to confirm all connections are made correctly.
