to a air compressor and to the pressure sensor and a switch?

Depends on if you have a positive starter solenoid or a negative starter solenoid. Basically you run the power wire from the battery to one side and the positive wire from the compressor to the other side. Then the smaller little knob gets either power or ground depending on which one you got. You run it to the pressure switch and Then either ground it or give it power. I ran a negative one if I remember right and I put a toggle switch in between so that I could kill the connection from the drivers seat. Always flip the switch when you get out of the car and you won't have to worry about the compressor turning on.

o ok i didnt know there was a + or a - one thnks
