PLANNING YOUR INSTALLATION
This is the most important step in your installation.
• Plan out the location of each component before starting your installation.
• Make sure you have enough airline and wire to install the system before beginning the installation.
• Make sure mounting locations are secure and void of debris.
• Try to keep the supply wire to the compressor as short as possible. Wires lose voltage over distance therefore
shorter wires will result in better performance.
• Mount your air source unit in a location that is as cool as possible and away from heat sources. This will make your
compressor run cooler and last longer.
• Your air source unit must be mounted upright with the compressor above the tank. Failure to mount the unit in this
position will allow any condensation buildup to drain back in to the compressor and harm its components, and also
will disrupt the compressor’s ability to cool.
• Teon tape or a locking compound should be used on every tting in your air system to prevent air leaks; unless a
white or red PTFE paste is already applied.
• Use the supplied 10 gauge wire or thicker (lower gauge #) wire to power your air compressor.
I. INSTALLING YOUR HORNBLASTERS TRAIN HORNS
The horns can be mounted in any direction and still be heard from all around. The horns should not be mounted
where they will be completely submerged or will receive any kind of impact. Horns may be mounted directly to your
vehicle, on a medium such as grommet strips (plumber’s strap), sheet metal or any sort of custom bracket. Note
that air line will be running to each horns rear mount.
1. Locate a secure, dry, and safe position for your horns.
2. Drill a 3/16” hole for the front mount of each horn and a 7/16” hole for each rear mount.
3. Secure the horn using the supplied mounting hardware.
II. INSTALLING YOUR AIR SOURCE KIT
Locate a at and secure installation area that will remain free of dust, dirt, and debris (your compressors performance
is directly a󰀨ected by air quality). Try to keep the distance of the unit from the battery to a minimum to keep your
compressor running at maximum performance.
1. Disconnect the ground cable from the vehicle’s battery.
2. Position the unit in the desired location and secure it using the supplied mounting hardware (10mm).
3. Remove the orange plug in the compressor’s inlet and mount the included air lter in its place.
SAFETY DURING INSTALLATION
• Disconnect the ground of your battery before beginning your installation.
• Use eye protection when operating drills.
• Take your time and do not rush your installation.

III. INSTALLING YOUR AIR TUBING & AIR VALVE
Before cutting any air tubing make sure to double check your measurements. Make sure to cut equal lengths of air line to connect
each horn to the manifold or the horns may sound at dierent times. We recommend cutting lengths with at least an extra inch per
line just to be safe. Unlike compression ttings our push to connect ttings can be used multiple times. The air valve should connect
to the center tting of the banjo tting. When threading any ttings make sure to use Teon tape to prevent air leaks. The air valve may
be mounted in any direction but it preferred that it is mounted vertically.
FITTING FLOW CHART
[Air Source] » [1/2” Line] » [1/2” to 1/2” NPT M Fitting] » [Air Valve] » [5/16” 4-point Banjo Fitting] » [5/16“ Line] » [5/16” to 1/8”
NPT F Elbow Fitting] » [Rear Horn Mount]
1. Plan out the ttings 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. Start by cutting equal lengths of 5/16” tubing to run from each horn to the 4-point banjo tting.
4. If the valve has a directional arrow on its body the arrow starts with the inlet and points out the outlet; the arrow should point
towards your horns.
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 tting.
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.
VALVE WIRING FLOW CHART
[Factory Horn Wire] » [Toggle Switch] » [Air Valve] » [Ground]
AIR SOURCE WIRING FLOW CHART
[Remote Wire/Accessory Wire] » [Inline Fuse] » [Air Source Unit] » [Ground]
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 ‘click’ 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 o upon reaching destination.

INSTALLING YOUR TRAIN HORN KIT (cont.)
IMPORTANT: The air horns and connecting ttings up to the outlet of the air valve will use 5/16” 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 ow and the damage is irreversible.
IMPORTANT: The air valve is directional and must be properly installed. There is an arrow on the brass body of the valve
that shows the airow direction, the arrow must point towards the horn. Improper installation will cause the
valve to malfunction and create a constant air leak to the horns.

Disconnect electrical components and drain you air system before performing maintenance.
GENERAL AIR HORN SYSTEM MAINTENANCE
• Check your air horns for debris when appropriate and at least once a month and clean when necessary.
• Drain your air system at least every other week, to remove any condensation buildup on the inside of you air tank.
• Make sure you air compressor is clean and free from debris at all times.
• Periodically change your two stage air lter on your compressor.
TIPS
• Make sure your engine is running when you air compressors are in use to insure proper voltage and to prevent damage to your
system.
• Do not run your compressor above its maximum rated working pressure. Doing so will not only void you warranty, but may also
damage your compressor.
• The air horns are pre-tuned to a locomotive chord and to their loudest possible tone. Do not adjust the tuning screw on the
horns. Doing so will void your warranty and may damage the horns if improperly adjusted.

2 GALLON SHOCKER INSTALLATION DIAGRAM
WARNING: To ensure the life of your system, reading and following these
instructions are recommended. Make sure to change lters and to drain the
moisture from your tank on a regular basis. Most factory horns are positively
activated. If your horn system is negatively activated, then you will need
to wire one of the leads from the value to a direct 12v power source. Then
wire the other lead to the megatively charged horn wire. Also if your vehicle
does not have an ignition positive source rated for 16AMPS, please use a
standard 40AMP relay.
