Re: 77 A/C Vacuum Diagram
What do you need to know? Wiring is connected in series. Power to low pressure switch -->high pressure switch ---> good ground. Power to low pressure switch comes from dash position switch. If low or high pressure switch activate, power to compressor is turned off.

I have everything wired, it is the vacuum hoses from the control head that I need a diagram for.
Thanks for the reply, FCS |

Re: 77 A/C Vacuum Diagram
Oh, miss read title. I'll have to check my 83 factory manual. It may a diagram. I don't think I've ever seen a vacuum diagram for A/C.
I searched a nice link on info but didn't find one there either. http://www.chuckschevytruckpages.com/ |
