I am in desperate need of an engine wiring harness for a 95 z28 with an lt1 and t56. Getting all sorts of wacky codes, pcm going crazy. I replaced pcm, and no change. After looking through the wiring, found all kinds of weird things goin on, spliced wires, things disconnected, broken or missing grounds, etc.... Someone hacked this thing up pretty good, and i hope a replacement harness will help. Any ideas where to look? Trying to find a decent used one, cant afford to go painless. Thanks!
