I'm stuck with this wiring issue. I have a obd1 gsrcar, but have a 99 obd2 b18c1 swap. Does anyone know the wiring of the engine harness? Or anything to contribute to this matter? Much appreciated!
use your OBD1 GSR harness. You will need to change/repin the distributor connectors. You will need to lengthen a few wires here or there.
The only wiring issue that is at all tricky are the IABs. The signal is reversed from OBD1/OBD2. I don't know exactly how to get around this other than a Skunk2 manifold or a logic gate.
Thanks. Do you have any diagram or instruction on a site where I can find? I know obd2 has more sensors, but can I use the obd1 harness and add a few wires for the other sensors?
