Ignition switch wiring on 72 pic please.

[Biohazard]

Well I have a plug/pigtail to wire in a stock ignition switch. When I got this bronco the PO had cut the plug off for one reason or another. I wired in a autozone universal switch to get by but I've gathered up enough parts to put it back stock. Now I'm playing the match the wires game and it's getting frustrating. I have a basic diagram of the 72 but no idea what terminals do what on the switch. My volt metered died, and my test light just decided to do the same. If anyone can get me a photo, I would appreciate it. I'm curious as to what goes on the extra terminal not included in the plug, and which one goes to the stud. Ideas?

Well got it wired up and everything seems to work. Not very confident in correctness of it because I have an extra red and yellow wire out of the factory plug that doesn't seem to do anything and isn't listed on the schematic. Guess I'll keep and eye on things and keep truckin.

Red wire went to the ambient temp switch in the door post. It goes on the stud.

This should be very close to everything you need:
