Engine Electrical Harness

After completing over 2000+ harnesses for Subaru conversions, we are pleased to offer a wiring harness modification service that allows your Vanagon to confidently and reliably run a Subaru powerplant.

With every harness we run a basic functionality test, checking for correct main and fuel pump relay operation. All wires to the vehicle are clearly marked and the alternator and A/C (if applicable) wires are tagged.

OBD2 harnesses include our interface board to help eliminate seven fault codes common on Subaru Vanagon conversion. Please note that some codes, for example with automatic transmission harnesses, may still be present - although they do NOT affect engine performance or operation.
