I have a 1981 mustang with 302HO carbed setup. I'm using electric water pump and contuer fans with manual steering. I bought a 6G alternator from EBAY for a 2002 mustang V6. I ran the main power through a breaker back to the battery disconnect switch but the 6G pigtail I bought to plug into alternator has a black, white and blue wire off coming out. Which wires do I need to use and to where? I have found a couple postings online that the white (center wire) is not used but nothing on the other 2.

Any help would be greatly appreciated. This is a ratrod style drag setup street cruiser NA\T5\lots of gear. lol

Most of us swap in a 3G, I know nothing about 6G.
Here's a link for a 3G

Here are a couple of wiring diagrams for a 6G:





You should be able to figure out how to wire it up from here.
