Hey guys/gals. I have a 1988 Trans am with 5.7 TPI. When I got it the wiring as all messed up from people messing with it over the years. I am getting feedback in the charging system right now. I am wondering. There is a plug with 3 wires and another plug on the back for 1 wire. How does this need to be wired? I currently have it wired with a new pigtail for the 3 wires, to their respective colors, and the 1 wire is going to the battery. Is this correct as far as the one wire? I was told on Camaro and Corvettes that there is a distro block or whatever that wires go to and then feed to the battery. Mine does not have this block.

 

 

this is no need for photos. There are 2 plugs on the back of the alt, a 3 wire-pigtail and a single wire with a rubber boot so it doesn't touch the valve cover. The single wire is going to the battery. The pigtail is wired into the wiring harness.

 

O,OK,you didn't mention it was the alternator in the 1st post.Yes,your wiring is correct.

 

Thank you sir
