Well.... based upon the responses I'm feeling pretty good about myself that this apparently is not a typical temp control unit.

Like I said, the AC system is definitely not from the factory so I wonder if this possibly isn't even a Mopar part. Maybe its a Chevy control unit?

Regardless - maybe I'm better off sending the truck to Classic Air or some professional shop and let them retrofit the whole entire AC and control system?

Has anyone done such a thing where you took your truck to a professional place and let them go through the whole entire AC system?

Thanks!
