HornBlasters AH-S4 - Manual

Planning Your Installation
If this isn’t the second time you’re reading the instructions, keep reading!
• 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.
• Make sure mounting locations are secure and void of debris. The horns are ideal for mounting under the
cab, along the frame rails, in front of your radiator, etc. To prevent your horns from being muffled, leave
plenty of space in front of them to allow them to project (horns facing down is ideal).
• The electric valve may be mounted anywhere in-line between the air tank and the horns but the less
tubing used between the valve and horns, the sharper the crisp!
• The horns should not be mounted where they will be submerged or will receive any kind of impact.
Installing Your Horns
• Drill a 7/16” hole for the rear mount first, then mark a location for the 3/16” front mount hole. When tighte
ning the panel nut for the rear mount and the nut for the front mount, torque only enough to secure the
horn firmly in place.

Installing Your Valve
• Locate the directional arrow on the valve body, for the direction of air flow. The arrow should point away
from your tank and towards your horns. On some valves the inlet port may also be marked as ‘in’ or ‘inlet’.
The air valve may be mounted in any direction but it is recommended that it is mounted vertically.
Wiring Your Valve
Once you have grounded one of the valve terminals, please choose one of the next two options for the switch.
• Option 1 (using a toggle switch & steering wheel): Wire the other terminal to a toggle switch and then into
your electric horn 12 volt line under the hood. This will let you blow the horns from the steering wheel
button with an On/Off switch.
• Option 2 (use a push-button switch): Wire the other terminal to a momentary button switch in a convenient
location and wire the other side of the switch to a 12 volt power source.
Test your solenoid valve by activating the switch. This should cause the valve to click if wired correctly.
