Description

This Rywire engine harness is designed for Honda B, D, and H-Series engines. It is similar to their Mil-spec harness but uses a single black wire color and expandable loom. It features new, pneumatically crimped connectors with white identification labels. Heavy interference circuits are protected and grounded. Each harness is 100% quality tested (pin-to-pin and resistance checked). It uses OBD1 (1992-1995) computer connectors but can be adapted for OBD2 computers (except USDM OBD2, H22, and GSR stock computers). Aftermarket computers with OBD2 plugs and non-US OBD2 computers are compatible. The harness includes a chassis-specific sub-harness, allowing for chassis changes by replacing only the sub-harness. It is warrantied and guaranteed to work but is non-refundable if installed.
