Two wires are usually needed on the pressure switch, one in the power coming from your control circuit, when the switch senses low pressure it closes the circuit and the other wire goes to the compressor motor.

Long discussion on the aux pump Posts 24 and 42 seem to be most relevant for wiring. Not sure if that 2008 chassis is "exactly" the same but "most" stuff carries over year to year with systems. There are several posts in the thread that discuss the "right" wire goes to...

I wrapped the open air vent end of mine with semi porous a/c filter foam years ago to keep road crud out...155k miles and it is still operable, dust it off lightly with a shop brush when greasing chassis.

Good Luck.
