Review on Four Seasons 36675 Mounted Pressure by Jonathan Robertson

The switch is perfect for my 1990 GMC Suburban Battery/Dryer. This switch is required for proper pressure change after changing to R134a. The factory wiring harness is different, so I bought a Four Seasons 37227 Harness Connector back then. I crimped the knife terminals onto the wires and plugged them into the factory wiring harness. I haven't decided yet whether to cut the solder shrink or just leave it connected to the terminals. That works great!
