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

This is the Rywire Mil-Spec Engine Harness, specifically designed for Honda F-series and H-series engines, and includes a chassis-specific adapter for EG chassis vehicles. If you're swapping one of these popular Honda engines into an EG Civic, this harness is built to make the wiring integration as straightforward as possible. It's constructed with Mil-Spec connectors and wire, which are known for their durability and reliability in demanding conditions, ensuring a solid connection for all your engine's critical sensors and components.

Rywire has put a lot of thought into making this harness a robust solution. The use of Mil-Spec components means you're getting wiring and connectors that meet strict military standards for performance and longevity. This is especially important for engine management systems where a single loose connection or a wire failure can cause significant drivability issues. The harness is laid out to route cleanly within the engine bay, and the included chassis adapter is designed to plug directly into your EG chassis's factory wiring points, simplifying the connection between the engine harness and the car's main electrical system. This approach helps avoid the need for extensive custom wiring or splicing, which can be time-consuming and prone to error.

When undertaking an engine swap, especially one involving a different engine family, the wiring harness is often one of the most complex parts of the job. This Rywire harness aims to remove that complexity by providing a purpose-built solution. It covers all the essential engine functions, from ignition and fuel injection to sensor inputs. While this harness handles the engine side, remember to verify that all other necessary components for your specific swap are accounted for, such as engine mounts, exhaust, and cooling system parts.
