What about the "high pressure switch", what is this thing doing or not doing? Be careful sir!

I'm looking for the high side pressure switch on the high side line cant find it on my 87f-150 4.9 liter it shows the switch on the a/c diagram that sylver 91 gave me. Im in the process of change my whole a/c system out. I've change my condenser and evaporater, dryer, a/c lines out. This weekend I'm changing the a/c compressor out to! I want to replace that high pressure switch too, i don't want any trouble!
