Installing A/C harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

69c10stepside · 01-31-2004, 06:35 AM

As my last two project trucks that I have had this bodystyle have only had non a/c cabs.. this newest one that I have been working on is a/c ready.. However, I dont have a clue where the a/c harness plugs into the main harness, and the sad thing is I didnt pay attention at all to it when I unplugged it (doh) If anybody can give me some pointers please do tell

Off to bed, Thanks for the help, Frank

On the 72's there are only two wires that plug into the fuse panel. The small gray wire plugs into the terminal marked panel lights and the large orange wire plugs into the ignition unfused terminal.

Thanks Guys! My next question was going to be about vaccum lines, but that diagram helped me with that also

Appreciate the help

Here are some more diagrams of the A/C that might be helpful.
I guess not,the attachment didn't work. It was a Adobe file.
