A/C Clutch Wireing on T/C 5.0 Swap December 01, 2004, 10:15:49 AM I finally got the turbo coupe wired tranny in and it runs. i have 3 wires that I cannot figure out what they do? I finally used a t-bird/ cougar 5.0 wireing harness out of a 88 cougar and the color codes on the wires with a little patience thrown in and a multimeter to wire the car up but i am to a point that I cannot figure out what a few wires do, first: light blue and pink or maybe orange, it goes to pin 34 or pin 37 on the eec wireing harness(i cannot remember), it is not used on the MAF computer and i did not hook it up. anyone know what this is for? second: there are 2 vss orange/ yellow wires that are on the 88 cougar wireing harness, I hooked one up to the turbo coupe vss wire inputs and the other is dangling and is not hooked up, do I really need this? and the a/c clutch wire(it is black on the cougar wireing harness), does anyone know what cooresponding wire that is in the wireing harness on the turbo coupe with the automatic temp control to plug it into? i only have a few wires to hook it up to that are left open on the turbo coupe harness? on my sport coupe the wires are the same color, should I just turn the a/c on inside the car and look for a hot 12 wire in the turbo coupe harness that was not hot before? if someone has already done this that would be greatly appeciated.
