Product Description
The Rywire RY-B2-BASE engine harness is a budget-friendly, clean-tuck solution for Honda and Acura platforms running B-Series or D-Series engines. It is engineered to simplify swap wiring while delivering a clean, minimal-wire engine-bay appearance. Using high-temperature Mil-Spec Teflon wiring, the harness provides reliability and heat resistance for daily driving or track use.
This modular design allows the main engine section to remain reusable, even when moving the swap into a different chassis. Labeled connectors, smart routing, and improved durability help ensure a smooth installation, whether you are refreshing an older swap or building a tucked engine bay for a show car. Choose the correct chassis adapter and any required plug converters to complete your setup.
