AC Compressor Replacment

Hey guys!

The air compressor in my 89 has a broken high pressure switch. I've got a spare 89 compressor that I don't really need, and I was wondering if I would wind up having to get the AC re-charged if I went to change compressors. I would assume that'd be the case, but I wanted to ask just incase there is some sort of a cut off valve that'd prevent the AC system from discharging when you went to change the compressor.

Other question, just how crucial IS the high pressure switch? Can I run the AC without it, or am I beggin to blow something up? For example, can I just put a timer on in place of the sensor, so it runs the AC compressor for maybe 20 - 30 seconds, then shuts off or something?

The compressor that is on there is good, its just the switch end that is broken off.
