Plumb the solenoid, 4-way banjo, and equal-length air lines so all four Shocker bells fire together.
Your horn kit includes the fittings shown below. Identify each piece before you start plumbing.
Thread one 1/2" NPT × 1/2" PTC (D) fitting into the tank. On a 2-gallon tank, this fitting only fits the end-cap ports. On a 5-gallon tank, any 1/2" port except the lowest (drain) port can be used.
Thread the other PTC fitting into the inlet side of the valve. The small arrow cast on the valve shows airflow — it points toward the outlet; the opposite side is the inlet.
Thread the 4-way banjo (C) into the outlet port of the valve. With the inlet PTC and outlet manifold installed, the valve should look like the photo.
Plan mount locations before you cut air line permanently.
Test-fit each bell, then find the center point between them — that is where the valve should sit so each banjo run stays short and even.
Cut the 5/16" roll in half, then cut each half again into four equal lengths. Uneven lines make the bells sound off at different times.
Thread an elbow (A) onto the brass stud of each horn. The elbows swivel — aim them to accept line without kinking.
Push a 5/16" line into each elbow and route it to the four-way on the valve. Avoid tight bends that kink the tubing.
Push the supplied 1/2" air line into the PTC fitting on the valve inlet, route it to the tank, and seat it in the tank-side PTC fitting. The horns are plumbed — next you will wire the air valve and relocate the air filter if needed.
Relocate the compressor air filter to a high, dry location so moisture never gets pulled into the intake.
Next article Help CenterYour horn kit came with this assortment of fittings below.
Start by plumbing one of the two 1/2" NPT x 1/2" PTC (D) fittings into the tank. If you are using a 2-gallon tank, this fitting will only fit into the end-caps of the tank. If you have a 5-gallon tank, any of the 1/2" ports (other than the bottom most port while mounted) can be used for this fitting.
Take the other 1/2" NPT x 1/2" PTC fitting and plumb it into the inlet side of the valve. If you are unsure as to which side is the inlet, take a look at the side of the valve.
The small arrow cast on the side of the valve indicates the direction of air flow that can pass through this valve. The arrow points towards the direction the air should be flowing. The side opposite from the arrow is the INLET, and the arrow always points towards the OUTLET.
Take the 4-way banjo fitting and plumb it into the outlet port of this valve. Your valve should look like the following:
Now that the valve is setup and ready to go, you can now start thinking about where you want to position your horns. Keep the following in mind;
Position each bell in the desired install location. Once each bell has been test-fitted in the desired location, find the center point between all of the bells. This is where the valve will be, so that each line from the 4-way Banjo fitting can route to each horn. Before you make the install locations of these components permanent, let's first make sure we have enough line to connect everything together.
Locate the roll of 1/2" and 5/16" air line that came with the kit. The 1/2" roll should be ~17' long, and the 5/16" roll should be ~10' long. You can cut the roll of 5/16" line in half. Take each half and cut it in half again, to make four equal length pieces. Make sure each length is cut evenly. If the lines are different lengths, the horn bells will sound off at different times and it will not sound nearly as good.
Take the elbow fittings (A) and plumb each onto the brass stud of each horn bell. These fittings can swivel and do not need to face any specific direction. You can swivel them around to accept the air line from the valve without kinking the line.
Once all four bells have the elbows installed, go ahead and connect one of the 5/16" air lines into the elbow fitting, and route it up to the four-way on the valve. Be careful not to kink the line by bending it too tight. Do this for all four bells.
At this point, go ahead and plumb the supplied 1/2" air line into the inlet side of the valve. Route the line up to your air tank, and plumb it into the 1/2" NPT x 1/2" PTC fitting. Your horns are now plumbed and ready for use. All that's left is wiring up the air valve!
Relocating your Air Filter is one of the most important steps when installing your HornBlasters horn kit. If you are mounting your compressor outside the vehicle, chances are it's going to get wet at some point in its lifetime. In this article we’ll talk about the steps to relocate the air filter
