So my A/C isn't working. The compressor doesn't come on at all, and upon further inspection, there are two wires with connectors (see first attached picture) on them coming out of the compressor, and they aren't connected to anything. I had my cooling system worked on this winter, so I'm thinking the mechanics at the shop knocked them loose. I found another loose wire coming from the high pressure line (see second attached picture) but I'm not sure which compressor wire it goes to. I haven't found another loose wire anywhere. Where should this other wire (which I assume is the power) be coming from?

Kind of guessing here but there should be a dark brown and black wire to the compressor clutch and a black ground wire.

The wire to the high pressure line is probably for the pressure transducer. The transducer should have three wires:
1: black/ light brown
2: violet/white
3: dark brown

If necessary, you can replace the transducer without discharging the system.
