I got pretty carried away doing the swap on the GL. I removed the alt harness too early on and I don't have any diagrams to help me install it. It's running as of now but I need to tie in the alternator to the car. I know the alt post puts off just over a volt but the 3 terminal connector on it I would like to connect and to the charge light on the car.

 

Any help would be appreciated! Thanks numbchux for the writeup and help!

Hi This is Jerry, i have a early legacy alt. and wiring set up that will plug into your car. Make me an offer, i live in Selah on the other side of the mountains. Call me 1-509-952-2855 Thanks Jerry

can't help unless you tell us what the EJ donor was. there are a number of different alternators and wiring.

It came out of a 90 legacy. It's being powered by a 92 legacy 2.2 harness

a quick searched turned up this:

Yellow wire get's switched power

 

Black/white wire goes to the charge light (white/red in the EA harness)

 

Fatty white wire in the plug should be direct to battery, same wire as the bolt on one.
