Ok, I just got my 85 Z28 with 350 carb setup back from the shop. Need alot of help. Had TPI setup before the 350 carb. Now I have wires hanging everywhere. Question can I take out all the old TPI wiring and ECM without any engine problems? Also need to know what basic wires in need for engine setup. Car runs fine now, but I'm afraid of all the wires out there not taped off or anything. Going the replace main compartment harness and engine if I can find setup from junkyard. Can I use any old Q-jet wiring and any year main body harness? One more thing, does anybody have pics or a decent wiring diagram of things listed? Hope someone knows.
