hello.. i am in the hopefully final stages of replacing the body on my 72 f-250 4x4. today i was trying to get the wiring harness back into place. when it came to the alternator. i honestly can not remember which wire went where. i took photos before tearing the truck apart, but can not find my roll of film. i think it only took two wires but my dad says there was a third wire on top.

 

scroll down a bit, this has a good diagram.
