Wolo 808 Challenger - Manual

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 sizes as shown in Fig. A.
3. Secure the horn with hardware provided. Tighten evenly to
provide a good water tight seal. Fig. A.
4. 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.
COMPRESSOR INSTALLATION
5. Install the compressor in a dry location. IMPORTANT: Compressor must be mounted not further than 8 to 10 inches
from the trumpet for proper sound.
6. To secure the compressor drill one 5/16” hole. When possible, mount the compressor (air
outlet at 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. B.
7. Using the plastic tubing
provided, cut to length and
connect the compressor to the
horn’s flexible inlet hose as
shown in Fig. C.
Caution: Avoid making any
kinks or sharp bends in plastic
tubing that will reduce air flow
and alter the horn’s sound.
WIRING
8. 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) terminals, 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 compressor.
B. For one (1) wire systems: If vehicle’s factory horn has one (1) terminal, simply transfer the wire to the compressor’s
positive (+) terminal.
C. Using wire provided or heavier 16-gauge, the compressor’s negative terminal is connected to any metal body bolt. A
ground connection should be free of rust and paint.
