My truck is a 1979 F150 2wd with factory AC. IM in the process of putting my dash wiring back in. Im wondering if somone could give me a diagram of the wiring going into the AC unit to the blower motor and the Diagram for the vacume operated dash controls.
THanks
Unfortunatly there there isnt a plug its just two prongs and the 3 wires that go to it can fit on it any way and in any order. The thing they are connecting to is a sensor with a brass peice of wire running to the AC unit.
this is most likely the switch that activates and deactivates the compressor based on the liquid reciever temperature, i will check my 74 factory ac and post back if you have not had success in the mean time.
If i had been smart and thought about the future 3 years ago i would have marked where all the connections go. I just bought a haynes shop book any it shows some of the diagrams, ill give it a look.
your a couple months behind me, otherwise I had my dash pulled out and could have easily got the info for you. I can still try to pull the ac controller if you can't find what your looking for.
