1973 F100 Alternator Harness

[JohnnyNash]

Hope you guys can help me. My father has had his 1973 Ford F100 since 1973 buying it new. I am trying to help him (due to his age to get it up in better shape). He had taken his alternator off and went and swapped it for a new one and when he came back home he couldn't remember how the wiring was hooked up. I was wondering if someone could take a look and advise me which goes where? I have attached the photos of the harness and also the back of the new alternator.
Thanks for any help you can give.
