The switch is either on the acccumulator or close to it. Just unplug it and short across the two wires. Don't run it this way for an extended period of time if it is low on freon as the compressor won't get lubricated and it will crater. GoodluckJoe

Black connector, back corner of passenger side engine, about 8 wires.
there are 2 sides, one with a clip and one without, on the side opposite the clip jump the two center wires.
It is probably just dirty, why not take it off and clean it, that way your car is safe, and everything still works like it should, I can add that your backup lights will work again too.
On the passengers side of the trans about even with the front of the door fan shaped switch held on by two bolts.
I suggest taking it apart and cleaning it before you think about replacing.
The switch is nearly $300
To remove, flatten out the retaining washer side under nut, remove large nut, remove smaller ( 14mm ) bolt on the adjustment side. Connector for the wires is top left of engine at the firewall, black connector with about 8 wires, you will need to snip 3 or so zip ties to get it free, the switch will slide off the bolt protruding from the trans..
cleaning is easy, 6 screws in back, pull apart, clean out all that old grease, pay special attention to the two contacts on the sweeper arm, they should move in and out easily as they have springs underneath and are the man contacts, apply new di-electric grease and reassemble.
reassemble and align before tightening, easiest way is to put trans selector in R and move switch until reverse lights come on.

Locate the low pressure cut out switch, unplug the wire connector, using a paper clip jump across the two connections in the electrical plug.

How do you check if the low pressure switch on a corvette 1977 is working?
Of which low pressure switch are you speaking? Engine oil pressure switch? If you're checking that, remove the oil pressure sending unit and temporarily put in an oil pressure gauge. If you're checking the AC low pressure switch, pull the switch from the AC low pressure line, Jumper the switch socket and see if the AC compressor comes on. If it does, you either have low refrigerant pressure or a bad switch. If you KNOW the pressure is up and everything else works, you have a bad switch.
