does anyone have a diagram of the entire setup for switch to compressor to tank to horn. any help would be great. i picked up a transport tank to use and im puzzled on how the air is released from the holding tank to the horn. is it just a pressure release valve? sorry if its a simple answer. but i would still love to see the drawing.

Yes, compressor fills tank, air valve (manual or electric) is connected to the tank and feeds the horns.
This one should answer some questions
