76 wire/plug heater question.

My son's 76 has factory ac. We have removed it to get out all the mouse stuff.
On his heater box on the interior of the truck, there is the heater fan resister.
There is a 3 prong plug that fits on three of the terminals.

There is a single terminal (that is part of the resister),,,that fourth terminal is the question. I don't know what wire goes to it. Can anyone tell me what color wire plugs on to this terminal?

My 15 year old son is learning the skill of recording what wire goes where before ripping things apart.

I can't wait for the vacuum line issues :-)

the wires will only fit on there 1 way. the main harness has 3 female prongs it goes on the top portion of the resistor and the lone wire goes on the bottom prong.

I figured out the three prog plug. Unfortunately, I have 3 "lone" plugs to choose from.

That's why I was asking what color is the wire.
