It depends on what vehicle you have, something you should put in your FTE signature so we don't have to ask.
Like what Monte and ND said, it's on the Dryer (Accumulator), and depending on what vehicle you have, it's either mounted on the side or top of the dryer.
Word of advice, don't get a cheapo low pressure switch. the PO put on a plastic threaded one on my van, and it was determined to be the leak in my system. We installed a heavy duty one with metal threads and a good seal and it hasn't leaked since.

2nd that. Also I should have specified that the diagrams I posted are for 1994.
