Hello, I am currently installing my new 12 SI alternator to my replace my stock one. I am following the directions in this thread -
http://67-72chevytrucks.com/vboard/s...d.php?t=119379
It is going failry well, however he states that there is only 3 wires running to the alternator in his harness, white red and blue. I have 4. White, red, blue, and black. I am assuming that the black is a ground? Is this ok to hook up to the alternator case as the stock one was? Or should this black wire not be there.. Thanks!
Engine: 250 IL6
