Default 1972 Corvette - Wiring diagram?

Looking for a wiring diagram for a '72 Vette w/ AC. Hoping someone would be kind enough to send me theirs.

Any help would be hugely appreciated.

Best,
Luke C

Herre is a copy I made from a file that I downloaded some time ago. It was in multiple pieces, and I put them together and then saved it as a PDF.
It is still in B&W as converting it to Color is a time-consuming process. I have not been able to check it for correctness as I have a 69 and not a 72.
Hope it helps.

I see that you were looking for AC circuitry in the drawing. As for as I know GM did not include that because it was an option.
I made an AC drawing for my 69, but I think you will find it very close to what you have as I think GM did not make many changes in the AC Circuitry.
It should be better than nothing.

I would recommend getting the diagrams that Doc Rebuild has. they are worth the money. they are colored and show what each terminal end looks like.

I agree that Doc Rebuild's laminated diagrams are great because they show the real world connectors!

What program are you using to color the diagrams?

Here's the diagram that Willcox distributed – it doesn't specifically say it's for '72, but that's the way it's titled in my references folder. Unfortunately this diagram is not the highest resolution and kinda fuzzy.

67:72 - I use MS Paint to redraw the wiring diagrams in color. It is an old and somewhat crude program, but it works very well to do pixel editing. After I finish them I save them as a PDF so that they can be copied easily and it is also more difficult for someone to re-edit them.
Even when I used to get paid for working, I would use it quite often. Once you make an image you can save it and then paste it into whatever document you are working on.
I have eight different graphics programs and each one has its own strength, but most of them are not that good at pixel editing.
For photos I normally use Photoshop and it has more functions that I will never use, but pixel editing is not one of them.
I have redrawn 1962, 1967 and 1969 wiring diagrams. I have copies that I downloaded of 1966 and 1973. Don't know who did them, but I will keep them.
I have redrawn many of GM's original drawings for my 1969 and cleaned them up and made them in color. I have put a number of them on the Forum.

i have uploaded quite a few PDF files to the Forum, but unfortunately, they do not have a separate place where you can put them, so they move down the screen and can become difficult to find.
I asked them if there was a place to store all of them in one place and they said No! Even I have trouble finding them sometimes. I have started adding a date to the file name so that I can tell if the file is the current one.
are you looking for any file in particular?

Interesting that no one has mentioned the wiring schematics are included in the Chevrolet Service Manual ( year specific). They are can be found on eBay at reasonable prices. If you are doing other repairs / maintenance, then I would strongly recommend getting a 1972 Manual.

Two of the problems with GM diagrams are that there are errors*, that Robertea has fixed when found, and his color-coding is much easier to follow than a spider web of black lines.

*GM's diagram for the '67 voltage regulator would create a dead short.

Doc Rebuild's OosooEze (or something like that) connector diagrams are well worth it when looking at a harness.

Tubbut: I have drawn wiring diagrams from 1957 to 1969. I have just finished 1966 but am waiting for a mid-year expert to look at it to see if I have made any mistakes in it. After drawing all of these lines it is difficult to see your own mistakes.
I haven't done any diagrams after 1969 because GM added so many changes that it is difficult to verify my drawings. It becomes very time consuming to double check for GM mistakes. I think when I did my 69 diagram I found about a dozen mistakes.
If you want one of the years that I have done, send me a PM with your email address and I will send you a copy. Bob
