III. Installing Your Air Tubing & Air Valve
Before cutting any air tubing make sure to double check your measurements. We recommend cutting lengths with at least an
extra inch per line just to be safe. Compression fittings use ferrules (olives) that should be used only once. When threading any
fittings make sure to use Teflon tape to prevent air leaks.

IMPORTANT: The air horns and connecting fittings up to the outlet of the air valve will use 1/2” air line. The air source unit will
use 1/2” air line to connect to the inlet port of the air valve.
IMPORTANT: Do not make any kinks in your air line. Doing so will disrupt air flow and the damage is irreversible.

1. Plan out the fittings placement out before you begin and make sure you understand the correct order.
2. Make sure that your tank is empty of air and that the compressor is not running during installation.
3. Install the air line carefully using two wrenches for each compression fitting. Use one wrench to hold the body of the
fitting stationary and another to tighten the compression nut.
4. Measure and plumb one length of 1/2” tubing from the tank compression fitting to the air valve located on the horn.
5. Next connect your air valve’s inlet port to your air source unit using 1/2” air line and 1/2” to 1/2” PTC fitting.
IV. Wiring Your Valve & Air Source Unit
Your train horn kit will use two completely independent circuits. One circuit will connect your horn trigger (push-button
intermittent switch, or toggled factory button) to your electric valve. The other circuit will connect your accessory trigger
(ignition positive wire) to your air source kit.

Circuit 1
1. Begin by wiring your horn trigger.
a. If you are intending to use your factory horn switch, start by locating the load wire of the horn button
(positive when horn is depressed in a standard vehicle) and wiring it to the included toggle switch.
b. If you are going to use a push button switch (intermittent toggle switch) wire a fused (5A) wire from any 12
volt source desired (battery) to your switch.
2. Next wire your switch to any pole of your air valve.
3. Wire the other side of the air valve to ground.
4. Test your circuit by activating your trigger and listening for a quiet ‘click’ sound from the valve.
Circuit 2
1. Locate an accessory line in your vehicle that is capable of a 16 amp load.
2. Wire your accessory line using an inline fuse (35A) to your air source unit (Red Wire).
3. Ground the other side of your air source unit (Black Wire) to ground.
4. Your air compressor system will not turn on automatically when power is on (Key is in ‘accessory’ or ‘on’ position) and
automatically turn itself off upon reaching destination.
