• Do not disassemble any electrical components of this horn kit (air compressor, air valve, pressure switch).
• Do not attempt repairs or modifications of any component. Please refer to qualified service agencies for all service and repairs.
• Do not operate any component where it can fall or be submerged into water or any kind of liquid.
• Do not reach for any component that has fallen or been submerged into water or any kind of liquid.
• Use the included components with 12 volt DC systems only.
• Do not leave the air system unattended during use.
  WARNING: To prevent injury:
• Never allow children to operate the compressor or air horn. Use close supervision when operating this equipment near children.
• The air compressor will become very HOT during and immediately after operation. Do not touch any part of the compressor with your bare hands during or immediately after use.
• Do not use this product near open flames, explosive materials or where aerosol products are being used.
• Do not operate this product where oxygen is being administered.
• Do not pump anything other than atmospheric air.

• Never point any air nozzle or air sprayer toward another person or any part of your body.
• The included compressor is equipped with an automatic reset thermal protector and can automatically restart after the thermal protector resets. Always cut off power source when thermal protector becomes activated.
• Use only in well ventilated areas.
• Do not sound the air horn(s) in close proximity to another person’s or your own ear(s).
• Do not fill the included air tank above 150 PSI. Doing so may result in death or serious injury.

INSTALLING YOUR TRAIN HORN KIT

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.
• Teflon tape or a locking compound should be used on every fitting 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.

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.

We recommend installing our kits in a certain configuration. With the 2 gallon tank, you have two 1/2” ports and four 1/4” ports. Install the tank in position where one 1/4” port is facing down for the drain cock. From there place the gauge, pressure switch and safety blow off valve in the remaining three 1/4” ports. For the two 1/2” ports, one of them will have the 1/2” to 1/4” female reducer bushing for the compressor (1/2” to 3/8” for the Viair 480c) and the other 1/2” port is for the 1/2” PTC to 1/2” NPT M fitting for the horns.

RECOMMENDED TOOLS

• 3/8” Long Socket (Horn Front Mount)
•  1/2” Long Socket (Horn Rear Mount)
• 1/2” Wrench
•  9/16” Wrench (1/4” NPT Fittings)
•  7/8” Wrench (1/2” Banjo)
• 10mm Wrench or Socket (Air Source Mounting)
• 12mm Wrench
• Drill (3/16” & 7/16” Bits)
• Wire Cutter/Stripper
• Tubing Cutter/Razor
• Eye and Ear Protection

INSTALLING YOUR HORNBLASTERS TRAIN HORNS

Locate an area for your horns that is dry and free from debris. 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.

INSTALLING YOUR AIR SOURCE KIT

Locate a secure area close to your air compressor to mount your air tank. The leader hose of the compressor should be able to reach an available port on the air tank with some slack.

1. Position the tank in its desired location and secure it using standard mounting hardware.

INSTALLING YOUR AIR COMPRESSOR PUMP

Locate a at and secure installation area that will remain free of dust, dirt, and debris (your compressors performance is directly affected 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 (8mm).
3. Remove the orange plug in the compressor’s inlet and install the remotely mountable air intake assembly. Using the included 3/8” OD air line and fittings you may relocate the air filter up to 6 feet away from the air compressor.
4. Only hand tighten the check valve.

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 different times. We recommend cutting your lengths with at least an extra inch per line just to be safe. Unlike compression fittings, the push to pull connectors can be used multiple times. The air valve should connect to the center fitting of the 4-point banjo fitting. When threading any fittings make sure to use Teflon tape or lock-tight to prevent air leaks. Some fittings may already have pipe sealant applied on their threads for your convenience. The air valve may be mounted in any direction but it is preferred that it is mounted vertically. Your tank has two 1/2” NPT ports and four 1/4” NPT ports. Your train horn kit should use one of the 1/2” ports and the other may be reduced to 1/4” reducer bushing if necessary.

IMPORTANT: The air horns and connecting fittings 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.

AIR COMPRESSOR TO TANK

[Air Compressor] » [1/4” Leader Hose] » [1/2“ to 1/4” NPT F Reducer] » [Air Tank]

1. Carefully connect the air compressor leader hose to the 1/2” to 1/4” NPT F Reducer bushing that is located on either end of the tank using Teflon tape or paste on the treading. When installing the leader hose DO NOT move the inline check valve located just above the swivel fitting.
   •  If installing a Viair 480c, you will use a 1/2“ to 3/8” NPT F Reducer.
2.  Locate a secure location to mount the leader hose using the bracket provided. Avoid locations where the leader hose may become tangled with wires and other hoses. a. When mounting the bracket, drill a hole with a 3/16” drill bit and put the self-anchoring hose bracket into the hole.

AIR HORNS TO TANK

[Air Tank] » [1/2” NPT M to 1/2” PTC Fitting] » [1/2” Air Line] » [1/2” NPT M to 1/2” PTC Fitting] » [Air Valve] » [1/2” to 4x 5/16” NPT M Banjo Fitting] » [5/16” Air Line] » [5/16in P2P to 1/8in NPT F Elbow] » [Rear Horn Mount]

1. Plan out the fittings placement 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 banjo fitting.
4.  Install your banjo fitting into the outlet port of your 1/2” air valve. 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.  Plumb each horn to the banjo fitting, making sure that the lines are inserted firmly into their sockets. You do not use Teflon tape or pipe sealant with the PVC fittings.
6. Finally connect your air valves inlet port to your air tank using 1/2” air line using the 1/2” M NPT to 1/2” PTC fittings. Make sure to use a side or top port on your tank so that condensation will not drain in to your air valve.

Air Filter Relocation

Your air compressor came with two barbed fittings and an air filter housing.

Let’s start by taking the fitting on the left with the male thread and inserting it into the compressor inlet. The other fitting (female end) can be threaded onto the filter housing directly. Your compressor/filter should look like the image below. At this point, you can use the supplied 3/8” air line to connect the compressor and filter together.

Route the air filter up to a high and dry location where it will not get wet or exposed to the elements. The compressor itself is fully sealed but if your filter gets wet, the compressor can pull water into itself and this will lead to problems later on down the road. Your compressor will last much longer if the filter is relocated to a high and dry location. Be careful not to kink the air line while routing the filter around.
*If your compressor is mounted outside where it is exposed to the elements, the filter MUST be relocated.
DRAIN COCK TO TANK:

1. Install the drain cock into the bottom 1/4” port on the bottom of the tank. If the drain cock already has sealant on its threads it is unnecessary to use Teflon tape on the threads.

PRESSURE SWITCH IN TO TANK:

[Air Tank] » [1/4” NPT Port] » [Pressure Switch unit]
1. Install the pressure switch unit into an available port on the air tank using Teflon tape or pipe sealant on the threading. Make sure to mount the pressure switch on the side or the top of the tank so that condensation will not be able to drain in to the pressure switch. Hand tighten only, and don’t tighten by twisting the box.

SAFETY VALVE IN TANK:

1. Install the safety valve into any spare 1/4” NPT port on your air tank. If the safety valve already has sealant on its threads, it is unnecessary to use Teflon tape on the threads. Do not mount on bottom of tank, and do not use as drain.

AIR GAUGE IN TANK:

1. Install the Hornblasters Air Gauge in the last remaining 1/4” NPT port using Teflon tape or paste on the threads. Make sure to mount the air pressure gauge on the side or the top of the tank so that condensation will not be able to drain in to the gauge.

 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 switch, or toggled factory button) to your electric solenoid valve. The other circuit will connect your accessory trigger (ignition wire, accessory wire) to your air source kit. If you have trouble with wiring, you can nd a wiring diagram of your vehicle on www. the12volt.com. This can help you locate certain wires to properly and safely install your train horn kit!

VALVE WIRING FLOW CHART (CIRCUIT 1)

[Factory Horn Wire] » [Toggle Switch) » [Air Valve] » [Ground]

CIRCUIT 1

1. Begin by wiring your horn trigger.
   • If you are intending to use your factory horn switch, start by locating the load wire of the horn button
     (positive when horn button is depressed in a standard vehicle) and wiring it to the included toggle switch (any side).
   •  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 (any side).
2. Wire your switch to any lead of your air valve.
3. Wire the other lead 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. Find the accessory line in your vehicle (this is a wire that is only powered when the key is turned to the
   ‘accessory’ or ‘on’ positions.
2. Using the supplied 18 gauge wire connect the accessory wire to the “BLUE ignition positive wire” from the pressure switch.
3. Ground your pressure switch using the small “BLACK wire” from the pressure switch.
4. Locate your 12v DC power source that is capable of handling a 26 amp load.
5. Run the supplied 10 gauge or bigger wire to the inline fuse holder using the supplied 35 amp fuse. Then connect this to the “RED fused 12v positive wire” from the pressure switch.
6. Connect the pressure switch to the air compressor using the “WHITE compressor wire” from the pressure switch to the “RED wire” from the compressor.
7. Ground the other side of your air compressor using the “BLACK wire”.
8. Your compressor system will now turn on automatically when power is on (key is in ‘Accessory’ or ‘On’ position) and automatically turn itself o upon reaching pressure limits.

2 GALLON SHOCKER INSTALLATION DIAGRAM

Horn Activation via Steering Wheel

The horn itself can be wired up a few different ways. If you would like to honk your train horns with the steering wheel, start by locating the factory horn. On most vehicles, the factory horn is directly ahead of the radiator, or mounted in a fender-well. Once the OEM horn is located, we need to find the positive wire connected to the stock horn. Using the supplied Scotchlok/tap connector, splice a new lead to the positive horn wire and route it over to a toggle switch
(optional). Route the opposite lead of the toggle switch out to the solenoid valve for your horns. You can connect this lead to one of the two wires on the solenoid valve for the horn. Take the opposite wire from the horn and route it to the frame as a ground point. At this point, press the steering wheel and listen for a click from the air horn solenoid valve. If you have air in the tank already, the horn should honk. If you need more assistance completing this connection, give us a call @ (877)-209-8179 or shoot us an email to [email protected]

Make sure the 5/16″ lines are equal length!Ensure each air line is fully seated over the compression fitting before tightening the nu down over it. If the line is not fully seated over the barb, it can slip off the fitting even with the nut in place. Hold the line in place and use a wrench to tighten the compression ferrule down.  The compressor filter must be changed out  every 2-3 months, otherwise the compressor will start to!pull in dirt/dust and wearprematurely. The filter!can be swapped out with three easy steps, as! shown below.
Use a flathead screwdriver to pry the filter housing apart. You can insert the flat end of the screwdriver into the seam, where the arrow is Remove the old filter element from the housing. Insert the new element into the center so  that the white portion of the filter lines up with the plastic tags replace the cove back over the housing, lining the tabs up on the sides of the cover

Wiring Instructions

Wiring the Relay

• Pin 30: This pin will connect to the battery positive terminal. You MUST use the supplied 10-gauge RED wire for this connection. Use the supplied tan or green terminal to connect the red wire to this pin. Cut our fuse holder in half to make two ends, and place this in-between pin 30 and the battery positive terminal.
• Pin 86: This pin will connect to a key-power source. This can be tricky if you’ve never installed our kits before. You are looking to connect this pin to any circuit that is ONLY ON WHEN THE VEHICLE IS ON. This will prevent your kit from running when the veh off. Common key-power sources include the cigarette lighter fuse, sunroof, radio, trailer running lights, daytime running lights, etc.
• Pin 85: Route a lead from this pin to the frame of the vehicle as a ground point. You may use the suppliedBlue or Grey wire for this connection.
• Pin 87: Take the red lead coming off the compressor/tank combo and connect it directly to this pin. Your relay is now wired and ready for use. You can use a small lead of wire to connect pins 30 & 86 together to test the relay. If you have this wired correctly, the relay should make a light ‘click’ sound when the two pins are connected. This means the relay is turning on and off properly. When you start the vehicle it will send power to pin 86 and turn the relay on, which will allow the compressor to run.

Key-Power-Source (Normal Method)

If you’re having trouble locating a fuse that is only hot when the vehicle is on, you can go online to https://fuse-box.info/. You can use a test light to check whether or not the fuses are hot with the key in the off position. Route the black probe/clip to the battery negative terminal (-) and use the red probe on the metal contacts of the fuse(s) you want to check. If the light comes on, your fuse is hot. If the light does not turnon, start the vehicle and check for current. The light should illuminate now that the vehicle is running.

Using A Toggle Switch Instead

You can use a toggle switch to ensure the compressor doesn’t run when the vehicle is off. To do this locate the supplied toggle switch that came with your horn kit. Wire one lead of the toggle switch to the output side of your inline fuse holder, and take the opposite lead of the toggle switch to pin 86 on the relay. When you flip the switch on, the relay will switch on and allow the compressor run. Wiring your kit this way unfortunately means that you MUST turn the switch off with the vehicle, otherwise the compressor coul run overnight and drain your battery.
