How's our set-up?

[mshafer1]

As MrForbes pointed out, you need a pressure relief valve on the high pressure side (compressor side of the chain with the pressure regulator being the divider) and the pressure relief valve needs to be configured (or possibly reconfigured) so that it allows the system to empty when it is opened.
As far as the solenoid, you do need to know if it is 12v or 24v, but to correct this it is just a jumper on the PCM this year.
You might want to upload a new picture as you make changes.

If your setting up to run the compressor off board (which is permitted under certain circumstances), you'll want to move your tanks down stream of the disconnect valve.
