I have a JDM B18C GSR that im putting in my 1992 Civic Cx Hatchback. The wiring harness clips on the B18C that come off the motor WILL clip into the clips on my CX harness that come from the firewall into the engine bay. But there are a few wires that run into the clips on the B18C, that don't run into the clips on the CX harness. Is this normal with this swap? P.S. Being the harness off the B18C will clip right into the clips on the CX harness does that mean it is OBD 1 like my car is? Also my CX harness that goes from the engine bay to the ECU clips right into my GSR ECU(p72). So does that mean the B18C and the GSR ECU are OBD1? Thanks!
