TRAIN HORN compressor *

[F3507.3POWERSTROKE>cumins]

I hooked up a toggle switch that has one wire coming from the stock horn, and one wire going to the solenoid on the train horns.. so that works good and when i flip it up it blows the stock horns, and down it makes the solenoid on the horns click, because i havent hooked up the air yet... but im a little confused on how to hook up the relay for the compressor.. i wanted to put an on/off switch on it so if the lines leak then its not constantly running, but i also wanted to hook up the pressure valve.. so when it hits 150psi it will shut off, then when it drops below 120psi it will kick on... so when i flip the switch for the compressor to on, it will run until 150psi then start running when it gets back to 120psi.. but when its off (like at night when im not using it) the compressor wont constantly keep going off and on..

any comments please
thanks

Run battery power to the main power connections on the relay. Then put a switched power feed through a manual switch and through a pressure switch in series feeding the "control" connection on the relay. Pretty simple, really.

I bought something like this to control my air compressor for my air set up. It's everything in one.
