My AC stooped working last year at end of season suddenly and I never got around to fixing. So now it's hot and I went to start checking and I cant find the low pressure switch? The only thing I see is a double plug on compressor. 1 with a single wire and 1 with 2 wires. Is the 2 wire plug the pressure switch built right into compressor?
Do you
have the same problem?

Oops! My goof. There are 2 plugs and both have 2 wires upon closer inspection. All three wires are dull washed green but 1 wire on upper plug seems slightly different in greenish color. The clutch wires are bright/saturated green and pure black.
