INSTALLING YOUR TRAIN HORN KIT

PLANNING YOUR INSTALLATION
This is the most important step in your installation.

  • Read instructions completely before beginning.
  • Most components and routing suggestions will follow, but before starting your installation we encourage you to become familiar with each item.
  • Make sure you have all components on hand to install the system before beginning the installation.
  • Make sure mounting locations are clean 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.
  • 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 that is outlined in these instructions. The instructions will apply to 99% of applications in stock form. Any modifications performed to the vehicle could change the way the horn kits fits and functions, HornBlasters is not able to predict and accommodate these changes,

INSTALLING THE WRANGO HORNS ONTO THE WRANGO BRACKET

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(1\)

First assemble the fittings on the 1/2″ electric valve. When holding the electric valve with the chrome bracket facing away from you, install the 1/2″ elbow fitting on the left side of the valve. Next you will install the 1/2″ to 3/8″ reducer into the right side of the electric valve, first applying Teflon tape to the fitting. Once installed, follow the reducer with the 3/8″ x dual 5/16″ splitter. Always double check the airflow of the valve by looking at the back. You will find a small brass arrow on the edge of the brass housing. This arrow should always be pointed towards the horns/splitter.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(2\)

Locate the two bells, air valve, fittings, hardware, air line, and horn bracket.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(3\)

It is important to place your horn bracket on a flat surface as shown. Position the bracket as seen in the picture. The shorter of the two bells will be closest to you. The longer bell and solenoid valve will be away from you. When you install the shortest bell first, the front mounting point of the bell will also be used as a mounting point for the solenoid valve. Remove the nuts and washers from the bell. On the larger brass fitting side of the bell, install into the lower hole of the mount. Once the brass fitting is through the plate, install first the washer, then the brass nut, loosely hand tighten. The front silver mounting bolt will also hold the electric valve in place. Place the front mounting bolt through the upper hole of the bracket using a washer on both sides and through the right hole of the upside down valve, loosely hand tighten. The left mounting hole of the valve will use the included 5/16” x 3/4″ hex bolt, washers and locking nut. Assemble as shown below.
Remove the nuts and washers from both mounting points. Install the second, larger, bell in the opposite direction.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(4\)

INSTALLING YOUR HORN KIT

Install two 1/8″ NPT x 5/16” PTC elbows onto the brass fitting. Hand tighten until only the black elbow piece spins. Then tighten one turn with 9/16” wrench.
Note: the front silver mounting point on both bells has two washers. Use one washer on each side of the bracket for the front mounting hole.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(5\)

Tighten all hardware.
Front, silver mounting lock nut is 3/8″ Rear brass mounting nut is 1/2″ Brass elbow air fitting is 9/16” Valve nut and bolt is 1/2″

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(6\)

Before cutting any air line, make sure to double check your measurements. Cut equal lengths of 18” of air line to connect each horn to the manifold or the horns may sound at different times. Unlike compression fittings, the push to pull connectors can be used multiple times. Run one piece of airline from the fitting on the valve to each elbow. Ensure not to kink or bend the air line too sharply. Cable ties have been included to secure the air line to the mount.

INSTALL THE COMPRESSOR ONTO THE COMPRESSOR BRACKET

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(1\)

  • With the L part of the bracket facing to the left and the compressor facing to the right, use the included hardware to attach the two pieces together.

  • Insert the bolts with a washer from the backside of the bracket, aligning with the mounting feet of the compressor. Install the second washer and then the lock nut. Hand tighten and repeat on all four mounting points. Once all four sets of hardware are in place, tighten using a phillips screwdriver and 3/8″ wrench.

  • The air filter for the compressor will need to be relocated. To assist in this, install the 1/4″ NPT to 3/8″ air line push connect elbow to the front of the compressor. Tighten to secure.
    This fitting will later be connected to the supplied 3/8″ air line and ultimately to the air filter housing.
    *Do not use Teflon tape on this fitting as the compressor can pull in small pieces of the teflon tape.

INSTALL THE COMPRESSOR ONTO VEHICLE
Your compressor will look different but install the same way.

  • Position yourself under the Jeep near the transfer case with 15mm socket, ratchet, and long extension.
  • Locate the three mounting locations on the transfer case. Inspect each hole, remove dirt and debris if needed.
  • Apply included blue thread-locker to the three (3) 3/8″ x 3/4″ hex bolts.
  • Attach the compressor/bracket to the transfer case use the three (3) hex bolts.
  • Torque three (3) bolts to the transfer case to 15 ft/lbs.

INSTALL THE HORN ONTO VEHICLE

  • Locate the two bolt holes on the cross brace near the rear axle. (Green circles) With the supplied 12mm hardware, use two bolts, two flat washers and two split lock washers to secure the end of the mount closest to the rear axle.

  • The end of the mount that is farthest away from the electric solenoid valve is pointed towards the rear axle.

  • Install the hardware in the rear holes and loosely tighten. You will need to leave enough play in the bolts so you can install hardware on the front side in the next step.
    Note: There is a black factory nut and bolt located on the middle cross brace.(Blue circle) Remove this nut, 13mm. Once the horn mount is in place, this factory nut can be used to hold the front of the horn mount in place while you install the tank mount. Additional picture on page 15.

PREPARE THE AIR TANK

Configuration of the components installed into the tank may differ depending on accessories and options chosen.
Please follow the fitting placement below for standard use, see image to the right.

  • Install the 1/2″ NPT x 1/4″ brass reducer bushing into the right end port, with Teflon tape. Then install the safety blow off valve into the brass reducer. Once installed, this fitting will be pointing to the front of the jeep and the closest to the air compressor.

  • Install the 1/2″ NPT x 1/2″ air line push connect the fitting in the left end port.

  • Install the 1/4″ NPT Drain cock on the bottom of the tank, with Teflon tape (between the legs of the tank) Install a 1/4″ NPT brass elbow fitting in the top port, with Teflon tape.

  • Then install the 1/4″ NPT to 1/8” NPT reducer bushing into the elbow, with Teflon tape. Install pressure switch. Point to the left, which is also the
    rear of the Jeep.

  • Install a 1/4″ NPT brass elbow fitting in the front right port, with Teflon tape. Tighten the elbow fitting so the threaded opening points toward the 2:00 position, see pic.

  • Install the gauge into the front left port, with Teflon tape. Position so gauge is level.

  • Secure the air tank to the bracket using the supplied 5/16” hardware. Insert bolt through plate and tank leg. Secure with flat washer, and lock nut.
    HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(12\)
    Optional: If using the Air Source Relocation Kit #90007 for the tire inflation see additional instructions on page 11.

INSTALLING THE AIR TANK
In this step of the install, you may need a second person to help hold the tank and mount.

  • Two of the M12 bolts, split washers, and flat washers are used to secure the tank mount. and the horn mount to the middle support of the Jeep. The M8 bolts, split washers and flat washers are used to secure the front of the tank mount the the front mount of the Jeep. Hand install 4 bolts until all are in place, then tighten all firmly.
    HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(6\)

  • The tank mount shares the same bolt holes as the horn mount where the two meet on the middle brace. The larger end of the tank mount faces the horn mount. Align and install the included hardware loosely until all four bolts are installed. Then tighten all four bolts firmly. Larger bolts are 19mm, smaller bolts are 13mm.

INSTALLING AIRLINES
Now that all major components have been securely installed on the Jeep, the remaining air lines can be installed. Before cutting any air line, make sure to double check your measurements. 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.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(7\)

  • Tank to Horn. The largest air line included with the kit, black 1/2″, will be ran from the elbow fitting on the side of the tank to the elbow fitting on the electric valve located on the horn.

  • Compressor to Tank. The air compressor comes with a stainless steel leader hose pre-installed. Route this leader hose from the compressore location on the transfer case to the elbow fitting on the side of the tank. Apply teflon and follow the torque specs listed on the compressor’s check valve.

  • Compressor to Air Filter. The other 3/8” air line in the kit has a glossy finish and is 6 feet in length. This will be used to relocate the air intake filter for the compressor. In step II-C, you already installed the 1/4” NPT x 3/8” PTC elbow into the compressor’s air intake. Press the black airline firmly into the elbow. Route the 3/8” air line to a location that will be clean and dry. The cleaner and drier the environment available for the air compressor filter housing the better. Install the chrome female 1/4” NPT x barb fitting onto the filter housing. Press the black air line firmly onto the barb fitting. Secure with attached bracket and/or cable ties.
    HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(15\)

WIRING YOUR AIR COMPRESSOR AND PRESSURE SWITCH
The horn kit can with two rolls of blue wire. Unroll both. Attach a red female wire connector to the end of each lead coming from the pressure switch. Connect each roll of blue wire to the connectors we just installed on the pressure switch. You can connect either wire to either side of the pressure switch.

These two (2) blue wires will have to be run towards the horns, and then up the firewall of the jeep towards the brake master cylinder, then cross over the engine department at the rear, ending up at the battery.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(17\)

NOTE: The routing instructions for the main red power wire (and part of the grey horn wires) will follow the same path. It will be easier to do them all at the same time, possibly taping some wires together. Included in the kit is a black 40 amp relay. It is suggested for the relay to be installed in a high dry spot near the battery.
Choose one of the two blue wire to be installed to the relay. Trim this blue wire to length and attach a red female wire connector. Plug this red connector into the #86 terminal on the relay.

The second blue wire will receive the micro add-a-fuse piece located in your kit. Connect this to the blue wire using the pre-attached blue butt splice, trim to fit. The add-a-fuse will come with a Yellow 20 amp fuse. Install this yellow fuse in the slotted location farthest away from the prongs.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(8\)

This blue wire with the add-a-fuse installed will be connected to the Jeep’s fuse panel located next to the battery. Remove the lid of the fuse box. Locate the fuse F57 or F58 heated seats, some models will have a yellow 20 amp fuse in place, but some models will have an unused empty spot.
If you have the yellow fuse in place, remove it from the fuse box and install the yellow fuse in on the slotted location below the new yellow 20 amp fuse. If you do not have the yellow fuse in place, move to the next step.
Now that the fuse location is empty, insert the add-a-use firmly, with the red wire lead of the add-a-fuse facing away from the motor.
Route the red wire lead, blue butt splice and blue wire towards the available opening towards the front. Slight modifications might have to be made to the plastic housing to ensure proper sealing and no pinching of the wire.

In the kit there is a roll of 10 gauge red wire. One end of the wire receives a yellow male wire connector. The connector will join to the red wire on the compressor. Run the remaining red wire towards the battery as described before. Trim the wire to fit so that it connects to the #30 terminal on the relay, using a yellow female wire connector.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(18\)

Locate the red fuse holder, cutting the wire in the middle of the circle. Attach a yellow ring terminal to one end. Attach a yellow butt splice to the other end. Using the 10 gauge red wire, trim to fit so that it connects to the

87 terminal on the relay, using a yellow female wire connector. At the end of

your installation you will insert the purple 35 amp fuse into this fuse holder.

Using an 18” piece of 18 gauge grey wire, install the larger red ring terminal to one end of the grey wire. Attach the red ring terminal to the ground side of the battery. Trim wire to fit and attach a red female wire connector so that it connects to the #85 terminal on the relay.

WIRING THE COMPRESSOR GROUND AND VALVE GROUND
The electric solenoid valve is made with two 18 gauge red wires, because it does not have polarity either wire can be positive or negative. Install red butt splices to both red wires. Using an 18” piece of 18 gauge grey wire, install the smaller red ring terminal to one end of the grey wire. Attach this red ring terminal and compressor ground ring terminal to a clean, bare metal, dry part of the vehicle frame with the included self tapping screw. Trim grey wire to fit and attach to a red butt splice on the valve.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(9\)

WIRING THE ELECTRIC SOLENOID VALVE
With the ground wire taken care of, run the 18 gauge grey wire towards the brake booster as described before. Use all the remaining slack in the wire to fold the wire on itself. To get the now doubled up wire through the firewall, locate the round black grommet opening below the brake booster.

Insert the two grey wires in a leftover piece of 5/16” air line from the horn assembly. Tape the wires to the air line. Fish the air line through the firewall far enough to grab the two wires, but making sure not to pull all the way.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(19\)

This will leave you one end of the grey wire to connect to your stock horn.
Locate the stock horn behind the grille and between the headlights, removing fasteners as needed. Peel back a small section of the wire loom. Using the red scotch lock from the kit, connect the your grey wire to the upper power wire going to the stock horn.

HORNBLASTERS-HK-S2JLU-238-Wrango-Horn-Kit- \(11\)

Installing the toggle switch inside the Jeep is the last step. Your horn button on the steering wheel will activate your Wrango horn too.
When the toggle switch is in the OFF position, only the factory electric horn will sound. When the toggle switch is in the ON position, both the factory electric horn and the Wrango horn will sound.

Included in the kit is a silver toggle switch with black wires. Install a red butt splice on both of the black wires. Locate the two grey wires you passed through the firewall, connect one grey wire to one of the black wires and the other grey wire to the remaining black wire. It does not matter which one you choose.
Lastly find a location to mount the toggle switch. Be sure to use a surface no more than 1/8” thick, and with enough clearance. First drill a 3/16” pilot hole, then a 7/16” hole. Insert the switch from the backside and secure with the included chrome nut from the front-side.

WRAP UP
IMPORTANT: Once are you parts are installed and system tested to be in proper working order, we encourage you to use the included cable ties and other methods to secure all wires, air lines and components. Keep all items away from heat producing and moving parts. Double check that you have tightened all fasteners and everything is secure.

INSTALLING YOUR TIRE INFLATION KIT (If purchased)

Locate the two ¼” NPT compression fittings. These fittings will be used to connect air line between the tank and air chuck that we will use with the 30′ coil hose. Apply teflon to both fittings before installing them.
Take a look at your air tank. There are no open ports available to install the tire inflation kit. A 1/4″ run tee fitting is included with the tire inflation kit. This piece will create a new port for the tire inflation components. Take a look back at page 9. The pressure switch can be removed from the tank along with the reducer bushing attached to it.
Go ahead and apply Teflon tape to the male thread on the run tee. Thread the run tee into the air tank and use a wrench to tighten it up. Adjust the tee so that the elbow portion of the tee points towards the bottom of the tank (where the legs are). Thread the reducer bushing and pressure switch into the 90* portion of the tee fitting.
Locate one of the two compression fittings pictured above. Apply Teflon to the male thread if you haven’t already and thread the fitting into the run tee. You can use a wrench to tighten it up.
Take the other compression fitting and apply Teflon tape to the male thread. Locate the L-shaped bracket that was packaged with the run tee and mounting screws. Position the air chuck and compression fitting so that the bracket is sandwiched between the two as shown below.

Use the included self-tapping screws to secure the mounting bracket to your vehicle. We typically see these installed near the license plate on the bumper for easy access.
The 30′ coil hose that came with your inflation kit can be used with the air chuck to fill your tires or blow out the vehicle with the included blowgun. Other tools can be used off of this system such as an impact, air ratchet, etc.
Your tire inflation kit is now ready for use. Be sure to keep the coil hose out of the sun when stored as it can
become brittle if left exposed to the UV rays for an extended period of time.
