Don 68

The switch on top of the heater box in my 68 has a two wire connector with a yellow wire and a green wire. The green wire was cut. I have looked in the AIM and cannot find this connector in the wiring diagram. Can someone identify where the green wire goes so I can get it reconnected? Also the car has air if that makes a difference. Thanks for the help.

Dark green wire on GM cars in the area of the pass side heater box area will virtually always be the wire to the AC compressor to trigger the clutch engauge
