My compressor had two wires feeding in from up front and a ground wire to the metal chase. one of the wires from the front was power from a fuse hot all the time. the other was from the HWH controller it feed a relay mounted on the compressor. only hot when the controller called for the compressor to run.

My auxiliary compressor was not coming on in my 2005 Dynasty. It was right in front of the drive axle passenger side. I removed it and checked it with a battery and the pressure switch was bad. found one on Amazon. I had a slow leak in the back and when the leveling system came back on it would let air out of other airbags to compensate for the leak but if it needed to add air the motor home would not stay level. when I was under it looking at the aux compressor I took some Windex and sprayed the solenoid manifolds one of the solenoids was blowing bubbles they were labeled and it went to the side that was losing air. replaced it and no more leak.
