If you're swapping a B or D-series engine with an OBD1 ECU into an early Honda chassis, this harness is built to make that integration much smoother. It tucks away neatly, keeping your engine bay cleaner and making it easier to work on.

Rywire is well-known for making these swap harnesses, and this budget version still uses solid, well-built components. It features a chassis-specific adapter, meaning it's made to plug directly into your car's factory wiring without a lot of guesswork. The harness itself is laid out to route cleanly, often tucking behind the intake manifold or firewall, which is a big help for achieving that clean, show-ready look or just simplifying your build. It handles all the essential engine functions, ensuring your OBD1 ECU can communicate properly with the engine sensors and fuel system.

It's designed to be a direct plug-and-play solution for the engine side, connecting your B or D-series engine to your OBD1 ECU and then to your specific chassis adapter. This means less time spent splicing wires and more time getting your project on the road. It's a solid option for anyone looking to get a B or D-series engine running in an early Honda chassis with an OBD1 setup.
