1966 Mustang 3g alternator conversion (help)

4078 Views 2 Replies 2 Participants Last post by  Explorer
I am doing the conversion on my 66 mustang v8 from the stock alternator to a 3g alternator from a 90s mustang. I got the pulleys all done and fitted, the volatage regulator switched out, but I am stuck at the wiring.
I ordered the kit from pa performance that retains the original wiring. It seems I have two more wires (other than main power and ground) on the back of my alt. right now. One white wire,and a black/yellow wire. What do I do with those two wires? Is one going to be my hot wire(ignition)?

Please help!

Thank you,

A couple more things. The case hits the dipstick tube, and the bolt head for the ground hits the block. Anyone else have these issues
Not sure what you mean by "voltage regulator switched out", as the external regulator is not used. You can "reclock" alternator by removing the three bolts holding it together and rotating case for clearance. Just don't allow case to come apart. Here is a diagram for a 3G alternator. Hope this helps.
