On a MPFI converted obd0 car you have 4 ground wires form the injectors running to the resistor box as well as one of the wires from the DX injector plug.

For obd1 injector wiring all you do is switch to the grey style harness plug so the injectors will fit the OBD0 harness, then take all grounds off the injectors and solder them all together with the one wire from the stock harness, so all 5 wires together right? Or i guess you could use the grey plug off the obd1 harness for that?

Thanks
