Default Need help with A/C compressor wiring

I am reinstalling the A/C compressor in my 76 thats been out for the last year. I need to know where the green wire with the white connector coming from the compressor gets connected. Thanks for the help.

That wire goes to a pressure switch located on the right side inner fenderwell on my 75. I would guess there is not much difference between 75 and 76?

my '76 diagram shows the green going to the pressure switch, next to the tan wire, like you say. It also shows another green coming from the compressor going to the idle stop solenoid. Both green wires coming from the same connector on the comp.

On my 79, the green wire goes to the idle stop solenoid to increase idle speed when the AC is on.

The solenoid is located on a bracket on the same side of the Rochester Carb where the throttle linkage is connected. These things are often removed and mis-placed by previous owners, or overlooked if the carb was changed. They were intended to prevent the engine from "dieseling" when shut off due to higher idle speeds required when the A/C was turned on.
