Installation -
Screw the WMS pressure switch into one of the 1/8 npt ports in your air tank. Connect one wire to a switched 12 volts. Connect the other to the positive wire on the compressor. You may still use your compressor toggle if you like. This will keep the compressor from turning on every time the tank is below 110psi. For instance, you may not want the compressor to turn on automatically every time you turn your key on and your air tank is empty. For this installation, take the wire from your toggle that goes to the compressor and connect it to one of the wires on the WMS pressure switch. Now connect the other wire from the WMS pressure switch to the compressor. Once you turn the toggle on, the WMS pressure switch will keep your tank full automatically.
