Yes - that's the pressure switch.

Test the switch for continuity with your multimeter (should have continuity between the pins if contact point inside is closed - no continuity means open due to bad switch or low charge.

Test for current at switch sockets - with engine running and a/c thermostat and fan on high. If no current, check smuggler's box relay and look to see if there has also been a fuse added somewhere (like near relay).
