Review on 💨 ACDelco GM Original Equipment 15-51343 Air Conditioning Refrigerant Pressure Sensor: Reliable and Precise Monitoring for Optimum Cooling Performance by Kuldip Roberts

When I installed mine I didn't notice that one of the A/C solenoid clutch connectors was pulled out and not making contact. This wasn't a switch bug; This sometimes happens with old car wiring. After the air conditioning system was completely filled with refrigerant, the compressor still did not switch on. The coupler was brand new, it had gas in it, so my mate got a flashlight and took a closer look, saw the connector pulled back, put it back in the correct pin. We turned the car back on and the compressor kicked in and immediately started cooling the car. The thing is, with electrical equipment in cars, simple things like loose plugs in dark places can derail your project if you don't test everything in bright light before wasting time plugging in a supercharger or alternator or something else blow, or charge it.
