Hi guys. So, I bought this vehicle listed above and the alternator went out. I accidentally ordered an alternator for a 2008 Equinox. I was wondering if I could get the Pinout diagrams for 2005 and 2008 alternator Electrical connectors and the alternator wiring diagrams for both years as well, in case I have to swap electrical connectors. I know it is just two wires, but I don't want to pop fuses if I guess wrong. Thank you.

Hi Alex,

It looks like there are different plugs, you should be able to get a new plug and wire it in or get the correct alternator. Here are the alternator charge plug pinouts. Check out the images (below). Please let us know what happens.

Okay, so would I put the one wire from the A,B,C,B connector Pinout into pin A or pin B in the other connector? The A,B,C,D single wire connector is on the vehicle and would be putting the wire into A/B connector which would plug into the alternator? Which pin is the generator turn on pin for 2008 alternator?
