Remove the pigtail... and then do what with it (to test it)?
Test the switch how?
All I have is a stanard digital voltmeter..... Do I test in Omhs?

remove the connector ,,,then short out the connector, then start engine , a/c on , fan on max , a/c on max, then with pressure gauge hooked up to low side monitor pressure,, and with ohm meter measure for zero ohms.at the pressure switch...then move switch connections to see if the resistance jumps....if this is solid zero ohms then with connector shorted flex connector and wires to see if the a/c compressor drops out...
