OBD2A to OBD1 ECU Jumper Harness

The SpeedFactory Racing OBD2A to OBD1 ECU Jumper Harness (SFR-01-041) facilitates the installation of a 1992-1995 Honda/Acura manual transmission ECU into OBD2A chassis vehicles manufactured between 1996 and 1998. This harness offers a true plug-and-play solution, eliminating the need for cutting or soldering, and ensures a secure connection with OEM-style ECU pin connections on both the ECU and chassis sides. Constructed with automotive-grade wire that surpasses OEM Honda specifications for heat and abrasion resistance, this harness is built for durability. Its extended leads provide flexibility for clean routing to the ECU location. Common applications include running a chipped OBD1 ECU for tuning on B-series or H-series builds, performing engine swaps where an OBD1 ECU is used in an OBD2A chassis, or maintaining the factory OBD2A engine harness while utilizing an aftermarket OBD1 ECU for Hondata, Crome, or Neptune tuning setups. Compatibility is specific: this harness is designed for OBD2A chassis (1996-1998 Honda Civic, Integra, Prelude, Accord, CR-V, and 1996-1997 Honda Civic del Sol) when paired with a 1992-1995 Honda/Acura manual transmission OBD1 ECU. It is not compatible with OBD1 automatic transmission ECUs, OBD2B chassis (1999+), or applications outside of Honda/Acura vehicles.
