OBA Wiring Diagram

I've looked around the internets and have never really found a good wiring/air line diagram for a OBA system. I'm wanting to mount up the 2.5 gallon tank and compressor in the back of the X. Probably the tank where the spare tire went (or somewhere close) and the compressor probably in the rear cargo area.

Anybody have any good wiring diagrams laying around? Or, just any overall advice? :D

What other parts did you get? Air line? Manifold? Pressure relay? This is a Viair system, yeah?

Here is an easy to follow wiring diagram that was supplied by Currie Enterprises when it was marketing onboard air systems using the Thomas 12v compressor. The diagram and parts listed will work perfectly with a Viair 400C compressor.

Note: The solenoid shown must be a continuous duty solenoid and not a starter solenoid. I have found that the continuous duty solenoid stands up better than a relay to the power surge when the compressor kicks on and amp load while running. Also, the "unloader valve" pictured is the same as a check valve.

Also, I need your opinions on this very bare bones, amateur sketch.

Does everything look okay? What wires go to what pins on the relay? I'm gonna have to ground the relay so I'm gonna need a 5 pin correct? Not indicated in my drawing but, I think I'm gonna keep everything (switch and all) in the rear cargo area except for the wire going to the Blue Sea of course.

For your relay you need to use the supplied pressure relay, and pipe one of the outputs of the tank to it. That air pressure is what tells the relay to turn off once the tank is pressurized.
