I need to see what wires go where from alternator and voltage regulator. I had to hard wire the voltage regulator because the plug was completely melted. I rewired everything and the truck is still not charging. The alternator and voltage regualtor are both new. Something in my wiring is still not correct. I got a full harness from a 83 with a oblong plug (Mine is round) Can I still use this harness or part of it?
