The standard wiring harness that comes with Air Lift’s 3H and 3P systems is only capable of providing power to a single compressor. This Air Lift 3H / 3P Second Compressor Harness allows you to add a second compressor to your system. Wiring is a breeze thanks to Air Lift’s built in relay holder. Just connect the second compressor signal wire into the original system harness and connect power and ground!
