COMPRESSOR MOUNTING
FIG. #1
1. Install the compressor in the engine compart-
ment in a dry location and safe from engine and
exhaust manifold heat.
2. To secure the compressor drill one 3/16 in. hole.
Mount the compressor vertically (air outlet on
top). Install the head of the bolt into the slot on
the compressor housing. Secure the compres-
sor to the vehicle using the lock washer/nut pro-
vided.
TRUMPETS MOUNTING
FIG. #2
3. Position each trumpet with open end facing down, mark and drill a 1/4 in. hole
for each trumpet. Secure to vehicle (refer to Figure B). Use mounting hard-
ware in order shown – spacer, lock washer/nut.
4. Important: Mount trumpets with the open ends facing down. This will pre-
vent water from entering into the trumpets and compressor. Water damage
to the horn’s component parts is not covered by our
factory warranty.
PLASTIC TUBING INSTALLATION
FIG. #3
5. Cut plastic air tubing to length, and connect trumpet using
the ”Y” provided.
Avoid making any kinks or sharp bends in tubing that will
restrict airflow and alter the horn’s sound.
WIRING COMPRESSOR
FIG. #4
6. Electrical Connections – Using Vehicle’s Factory Horn
Switch
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 a vehicle’s factory horn has
two (2) terminals, simply transfer the wires to the compres-
sor’s terminals.
IMPORTANT: when testing the horns, if compressor motor
turns on but the horn does not sound, reverse the wires
connected at the bottom of the compressor.
B. For one (1) wire systems: If a vehicle’s factory horn has one (1) terminal simply transfer wire to the compressor’s
positive (+) terminal.
With compressor off, remove
tube and put a few drops of light
oil (SAE-10) into the
opening every 6
months.
Run
compressor to lubricate.
