Rywire RY-B2-EF B/D-Series OBD2 Budget Tucked Engine Harness for 88-91 Civic/CRX

The Rywire RY-B2-EF is a budget tucked engine harness designed for 1988-1991 Honda Civic and CRX (EF chassis) with B-series or D-series engine swaps. This harness features OBD2 engine side wiring for injectors, alternator, and distributor connectors, while utilizing OBD1 (1992-1995) ECU plugs for compatibility with Hondata, KPro, and aftermarket engine management systems.

Key Features:

• Single black wire color with expandable loom for a clean, tucked appearance
• New connectors with pneumatic crimps and white identification labels for easy installation
• Includes matching EF chassis jumper harness that plugs into factory dash and shock tower connections
• Heavy interference circuits protected and grounded, 100% pin-to-pin and resistance tested
• Two-piece design allows engine harness to be moved to another EF chassis with the appropriate adapter

Important: This OBD2 version uses OBD1 ECU plugs and will not support USDM factory OBD2 ECUs, but works with aftermarket ECUs using OBD2 plugs and some non-USDM OBD2 computers. Injector adapters, alternator adapters, distributor adapters, and charge harnesses are sold separately. Made in the USA.
