[69RustyBucket]

Hooked up my wiring to my compressors and switchbox, relays etc. When I turn the key on the compressors turn on, I have acc power to the pressure switch and to the relays. The av7 switch box came with remote wires that were color coded and plugged them all in. hooked up power to the accuair. Hit the switch box buttons and nothing.
The tanks had air. Everything is brand new. Any ideas. Checked the grounds.
