I'm in search of a AC wiring diagram for a 1991 Chevy chassis, Cobra motorhome. Specifically looking to see where the 2 wires that come off the pressure switch are controlling. Any help would be greatly appreciated.

Welcome to the forums!

One wire to the pressure switch is from the dash, hot when A/C or Defrost is selcted. The other wire goes to the A/C compressor clutch. On your '91, the switch is a combo hi-low, disengaging the compressor if pressure exceeds either limit.

I assume you have a Class C; manuals for the '90 or '91 Chevy van will have most of the diagrams you need. I prefer the Haynes.

Alldata offers online manuals.

Thanks for the info Rusty - - My Cobra is a Class A, 28 ft., on a P-30 (?) chassis. I will check the wiring tomorrow.
