Re: serpentine conv ?

The backside is a high pressure switch. You definately want it wired. Otherwise you will blow up your lines. Wire it in line with the low pressure switch. The low and high pressure switches are wired in series. If either is switch is activated, the compressor is shut off.

Take the hot out wire from the low pressure switch. Wire it to one side of the high pressure side. Wire the other side to the hot compressor wire. Wire the ground compressor wire to a good ground.

you will need 2 make or buy a plug with resistor, depending n whether you have a light or gauge. i bought the plug end from an alt. shop, and the resistor from electronic store, but if i do it again ill just by the adapter
