Philco wiring question

Sorry dad put a aftermarket in years ago

Thanks, I have a wiring diagram myself, it just doesn't make any sense... to me.
It was a giant p.i.t.a. to get that thing outta there, I think I'll just try for a block off plate for the original location,
or put the dead philco back and put a newer system inside the glove box.

While we're on the subject of wiring, anyone know what the green wire in the frigette a/c goes to?
Getting that to work would be something else.
Thanks again,
J
