Product Description

The BLOX Racing BXAC-00702 is an OBD2B to OBD1 ECU jumper harness designed for Honda and Acura enthusiasts running engine swaps or high-output builds on 1999-2002 OBD2B chassis. It allows a direct, plug-and-play connection of a popular OBD1 ECU - such as the P28, P30, or P72 - into an OBD2B vehicle without any cutting or soldering. This conversion unlocks significantly greater tuning flexibility over the factory OBD2B ECU, making it a standard foundation for turbocharged, supercharged, and heavily modified Honda K- and B-series builds.

Built with silicone fiber-reinforced wiring and individually pinned connectors, this harness is engineered to outperform standard aftermarket wiring in heat and oil resistance while keeping all factory sensors fully operational. Compatible with 1999-2000 Civic, 2000-2001 Integra, 1998-2002 Accord 4-cyl, and 1998-2001 CR-V - manual transmission only. For OBD2A chassis applications, see BXAC-00701.
