I took down my ac cover when doing my headliner and 6 months later I can’t
find my photo of how the wires connect on the back side of the controls.
Does anyone have a photo of this or able to help?

Here are a few pictures of the AC controls. Roof top unit says Mark IV. Can anyone help me with the wiring connections? I cant find the reference picture that I took before I removed this interior cover.

Sorry to hear of your misfortune. But I learned a few years ago, before I disassembled anything on the coach, I grabbed the cell phone and took photos as I disassembled it. With the age of these coaches and the many owners, it is difficult to assume anything is done OEM style.

Perhaps an on line search might find the original installation manual.

I also take tons of reference photos....to avoid this. :) I must have
accidentally deleted it. I have looked and looked.
I was hoping that someone here has the same unit and either had a pic or
could take one. Appears as though this is not a unit that was used on many
coaches. I asked GMC Bob Dunahugh about it and even Bob didnt recognize
it..... and he knows about everything!! LOL
I have a friend that is an electrical engineer that is planning on stopping
over to look at it... Hopefully he can figure it out. I hate to plug it in
wrong and burn something up.
A name plate on the unit says John Mitchell Co. Dallas Texas. It looks
like this company closed in the early 80's
I have looked online and cant find anything about this unit.
