I used my OBD2 injectors with the OBD2 wiring harness. They plug right into the fuel rail and engine no prob. I am also running the OBD1 Pr3 that came with the engine connected with an OBD2->OBD1 wiring harness i got on ebay for $50. I have an OBD1 dizzy with a homemade jumper to my OBD2 harness. Everything runs great. Compared to how the car used to, I am loving it. Have yet to take it to the dyno, probably will thursday.
