One way to do this is as follows -
- Install a storage tank with pressure switch. 3-5 gallon or so should be fine. One with multiple large (1/2" minimum on the largest) openings would be best.
- Plumb and wire the compressor to fill the tank based on the pressure switch.
- Plumb each bag (or group of bags depending on your setup) through a solenoid valve connected to the tank. Place a T fitting inline between each valve and the bag. These valves need to be wired to your inflate switch in the cab.
- Install a solenoid valve in the open side of each T installed in the last step and wire to the deflate switch in the cab.
- In the largest opening in the tank, install a fast opening, or dump, solenoid valve.
- Plumb your horn to the valve using the least amount of tubing and at least 1/2" diameter if possible. The intention is to get the most air to the horn as fast as possible. A larger tank will allow the horn to sound longer, louder.
- Wire this solenoid to the horn switch of your choice.
- Have fun scaring the pants off of people with your new horn.
This is based on a set of generic conditions. Your components may or may not function properly with this, but I encourage you to give it a try and make it work. Hope this is what you were looking for.
