Rywire Honda B-Series OBD1 Tuck Budget Engine Harness w/Chassis Specific Adapter

This is the Rywire B/D-Series OBD1 Tucked Budget Engine Harness, specifically made for the EF chassis with a late model chassis specific adapter. If you're swapping a B or D-series engine into your EF chassis Honda and want a cleaner look with your wiring, this harness is designed to help you achieve that tucked engine bay aesthetic. It routes the wiring through the firewall, keeping it out of sight for a much neater appearance.

Rywire is known for making solid wiring solutions for Honda swaps, and this harness is built with that reputation in mind. It's designed to be a direct fit for the specified EF chassis applications, meaning it should plug into your factory OBD1 ECU and your engine's sensors without major modifications. The 'budget' aspect means it focuses on the essential tucking functionality without some of the more advanced features found on higher-end harnesses, making it a practical choice for many builds. This harness is designed to work with the factory OBD1 ECU, so you'll need to ensure your engine and ECU are compatible with that system.

When installing this harness, you'll be routing it through the firewall to achieve the tucked look. This means you'll need to carefully plan your routing and ensure proper sealing where the harness passes through. It's a great way to clean up the engine bay, making it easier to work on and giving your build a professional finish. Make sure you have your OBD1 ECU and compatible sensors ready to go before you start the installation.
