i'm starting to hook up my on board air and was just wondering where to get a pressure switch to turn off my compressor @ 120 psi and to kick back on @ around 100 psi thanks in advance

I got mine at KMS; on at 85, off at 125 lbs.

Make sure you also get a oneway check valve and mount it on the inlet of the tank. It will take the strain off the ring in the compressor and protect the air supply if you bust a line.
You also want a pressure relief valve. 150psi is standard.
