almost everything is available in the form of raw parts, you need to be creative and put them together.

It is a Sanden (4402) SD7H15. I wish I would have kept all my components from my last truck to do the install on the new truck. Prices have went up so much. I am going to see if one of the AC distributor/builders in Phoenix can rework a standard FMTV box and add the AC components if I build the box out the same size as the one that comes with AC.

Just finished installing the AC on my lmtv... I have a slight problem with the AC off the engine fan cycles perfectly at 200°.... When I turn the AC on it's short cycles and will overheat

There is no connection between the A/C and the engine fan. Did you connect any wires t o the fording switch?

Good question. Yep, there should be no connection between the two. The AC controls it’s own condenser fans and the engine fan control should control itself like it always has.
Now if someone got creative and tried to mix in the fording switch to also disable the condenser fans, they may have inadvertently powered the engine fan solenoid from the A/C system which would have disabled the engine fan every time the A/C condenser fans are commanded on(each time the A/C cycles on)... You see the engine fan and fording control is inverse. Power applied thru the fording or thermal switch = engine fan OFF...

In the upper left corner of the instrument panel is a switch that will apply 24v to the fan control solenoid valve and force the fan to freewheel/keep it from engaging. It is for driving into/fording deep water where a coupled fan might get damaged…

Unfortunately I got the pre-wired kit from advanced automation out of Texas..... It was all three wired pretty much plug and Play unfortunately there was one wire that wasn't lately when I called him he said he can go to a switch which I didn't understand or ground..... And there's no wiring diagram

The other issue that I'm having is the dash switch lights none of them light up anymore and my turn signals quit. I also have a deuce and a half and a Humvee. The first time I tried to pull something with both the vehicles there were some 12 volt lights in the trailer. They seem to have took out the signal flasher. On the deuce and half and the Hummer it's the same flasher. I know the m1078 has 24 volt and 12 volt connections but when I had to tow my Jeep with it that's what it seemed to quit. And I will rerun that wire just to see what happens.... hope it solves my problem...

Hate to hear it, but there is a spreadsheet maintained by one of our members. Great resource for replacement parts or just the part number for a flasher maybe...
LMTV/FMTV Quick Parts Reference Spreadsheet
https://docs.google.com/spreadsheets/d/1U0XMs6blh-7a6B3IIe-A7GKcAHEj5-6hZEghH_jddgw/edit#gid=0 I just started doing this tonight. I have about 3 or 4 hours into it so far. I am going thru threads and pulling up part numbers people have posted as well as running NSN's myself. If you have any...

Information on the flasher is Line #80 in the spreadsheet linked above.

I'm all new to this thank you for the link that's awesome... I've had these trucks for a while Stewie never gave me a problem until I finally tried to install the AC... Unfortunately I use her to call the dead cows to the dump they can bury him we can't

Glad to help.
Don't hesitate to ask questions. Most everybody here jumps in and wants to help. The more details you can give - the better answer you will get because guessing is hard work
I hate to hear that your truck has to be on Morgue Duty for the cows.
Hopefully that doesn't have to happen often.
Guess your Stewart does that job well - and a little water hoses down the bed afterward and makes her like new again.
