Will you still be able to open the box with the horns there?
Oh, and not that this will help you understand anything, but you should use a relay with a key on wire to the compressor so that if your truck sits for a few days and the prressure gets low the compressor doesnt kick on and kill your battery. thats how mine is and works prefectly. Just kicks on if the pressure drops below 120 psi and kicks off at 150 psi but only if the truck is on.

The pressure switch wires should all be labeled.
One you will want to be connected to a switched power source, put a toggle switch on it too so you can keep the compressor from coming on if you want.
One you will want to come straight off the battery, that will be the power wire for the compressor.
One will connect to the positive lead on the compressor.
And the last will be ground.
For the valve I recommend just pulling direct from battery too (obv you need to add a fuse to the wire too) and running a momentary switch on it, I had my old setup wired to the stock horn and didn't like it. My new setup is wired to a momentary switch from radio shack and its much better. I've done 2 seperate train horn installs on my truck so if you need any help LMK.
