ive got a 351w powered 87 coupe. A buddy of mine give me a alternator like the ones that come on 01 v6 mustangs its a 105 amp. I got my hands on a wiring harness from an 01 hooked it up to the best of my ability. Theres the big charge wire which i have ran to my starter solenoid. then there 2 other plugs on the alternator a small white one which has one wire and the other plug which i believe has 3 or 4 wires in it. i dont have any of these wires hooked up. should i to make the alternator charge and my volt gauge to work!!??
