Wolo 809 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 size shown in Fig. A.
3. Secure the horn with hardware provided. Tighten
evenly to provide a good water tight seal. Fig. A.
COMPRESSOR INSTALLATION
4. 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.
5. 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.
6. Using the plastic tubing provided, cut
to length and connect the
compressor to the horn’s inlet fitting
between the trumpets 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
7. 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.
