New to the forum guys. Have a quick question though..Ive been working on a 86 MC for a while now and Ive gotten stuck with some wiring I put a 350 in and i know i wont need all the ECM wires from my original engine, I ordered 3 different harnesses already none seem to work or there either missing a key sensor that I need if anyone has pics they could post under the hood or can direct in the right direction as far as the sensors that must be plugged in then that would be great thanks guys....This is a huge project for me also, pics coming soon by the way.
