Rywire budget D-series and B-series compatible wire-tuck engine harness offers a replacement engine harness for D and B series engines.  The single black wire color and expandable loom saves costs and keeps the price down. This harness is designed for use on OBD2 engine set ups (OBD2 distributor, alternator, etc.).  However, the ECU connector style is OBD1, so this should be used with an OBD1 ECU only.

All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering.   Rywire engine harnesses are 100% quality tested pin to pin and resistance checked to ensure no voltage fluctuations.

This harness is designed for a more universal fitment.  The engine harness connects to all necessary connectors on the engine, and to the ECU plugs.  The harness includes a 'C101' connector which will route to your chassis for necessary chassis connections.  See our Chassis adapters to make your harness install easy!
