OBD1 connector form your local chevy dealer will be less than 20 bucks. I did my lt-1 harness. I'm an electrical idiot. If I can do it, anyone can. Get a copy of the factory wiring diagram or use the linked hybrid Z thread. Put it on a kitchen table, remove all the loom, remove the wires you don't need and you will be amazed at how simple it is to get that motor to run in another car. Good luck.
