Hey all, I'm still working on the air horns & wondering where the air horns get there air from ?
the horns get their air from the solenoid on the back of the air pressure gauge on the dash. air pressure is supplied to the gauge from the air tanks
When my air horns quit the problem was the wire in the steering wheel. We just pried it up with a knife and resoldered the wire and "viola!". :P
