AIR HORN INSTALLATION
1. Locate the desired area you wish to mount the dual trumpet air horn. For best
results, the front of the horn should be unobstructed so that the sound can carry
straight ahead.
2. Use the horn’s rubber gasket as a template. Mark hole locations and drill to size
as shown in Fig. A.
3. Secure the horn with hardware provided. Tighten evenly to provide a good water
tight seal. Fig. A.
IMPORTANT: Be sure to use the rubber gasket to protect against water leaks.
4. Position the front trumpet support bracket around the narrow part of the trumpet.
Push the bracket forward until it is tight. Use
the bracket as a template, mark hole loca-
tions and drill to size. See Fig. B.
5. Secure the front trumpet support bracket
with the hardware provided.
IMPORTANT: Be sure to use the rubber
gasket to protect against water leaks.
6. Secure the flexible inlet hose into the
base of the horn. Do not remove the
Teflon tape on threaded end of hose. The tape is used to prevent air leaks.
7. Install the tank and the trumpets back onto the horn’s base. Only hand tightening is
required.
COMPRESSOR INSTALLATION
8. Install the compressor in a dry location. IMPOR-
TANT: Compressor must be mounted not further
than 8 to 10 inches from the trumpet for proper
sound.
9. To secure the compressor drill one 5/16” hole. When possible, mount the compressor (air
outlet on top). Install the head of the bolt into the slot on the side of the compressor. Secure
the compressor to the vehicle using the lock washer/nut provided as shown in Fig. C.
10. Using the plastic tubing provided, connect the compressor to the horn’s flexible inlet hose
as shown in Fig. D.
Caution: Avoid making any kinks or sharp bends in plastic tubing that will reduce air flow and
alter the horn’s sound.
WIRING
11. Electrical Connection – Using
Vehicle Factory Wiring
IMPORTANT: You are not required to
use the relay supplied with the kit
because the vehicle factory system already has a relay.
A. For two (2) wire systems: If vehicle’s factory horn has two (2) ter-
minals, simply transfer wires to the compressor’s terminals.
IMPORTANT: when testing the horn if compressor turns on but
the horn does not sound, reverse the wires connected to the com-
pressor.
10. B. For one (1) wire systems: If vehicle’s factory horn has one (1) ter-
minal, simply transfer the wire to the compressor’s positive (+) ter-
minal.
10. C. Use16-gauge wire or heavier, the compressor’s negative terminal
is connected to any metal body bolt. A ground connection should
be free of rust and paint.
