    Can OBDII coils and ignition harness be used with OBDI

    Can the OBDII coils and harness be used on an OBDI swap?

      Yes. I'm running them like that.

          Absolutely correct.

          Only difference is that the OBD1 ones seem a bit larger and heavier and have 4 bolt holes instead of 2. Otherwise they operate exactly the same and are plug and play interchangeable.

          Fitment isn't perfect but they work good.

                  Coils yes, coil harness no. You use the obd1 coil wiring that's integrated into the harness

                          They don't quite fit right but they work if that makes sense.

                          You might need to use washers or something to make them fit properly.
