before it is packaged. If you need help installing your new Wolo horn, our technicians are available to answer your

(4676).
HORN INSTALLATION (Fig. A)
1. Locate a mounting location that is a solid metal surface such as the
vehicle’s frame or chassis to help prevent excessive vibration, which
could damage the horn. IMPORTANT: Do not mount horn on a plas-
tic fender well or flexible material. For best results, the front of the
horn should be unobstructed so that the sound can carry straight
ahead.
2. Use the base of the horn as a template, mark the hole locations and
drill to size.
3. Place the gasket between the mounting surface and the base of the
horn.
4. Secure the horn with the hardware provided and tighten evenly.
HOSE INSTALLATION (Fig. B)
5. Use 1/4" O.D. plastic hose (not provided), cut to size in order to connect the
horn’s electric solenoid valve to the tank of the vehicle’s high pressure on-
board air system.
6. Place the brass nut onto the end of the air hose. Push the hose onto the
male inlet fitting located on the electric solenoid valve.
7. Thread brass nut onto the male fitting and tighten. CAUTION: Do not over
tighten brass nut.
8. Connect the other end of the hose to the vehicle’s on-board air tank. Make
sure that the on-board air system has no pressure before attempting to con-
nect hose to tank. IMPORTANT: NEVER INSTALL THE HORN TO AN AIR
TANK THAT CONTROLS THE AIR BRAKES OR ANY OTHER CRITICAL OPERATING SYSTEM.
ELECTRIC VALVE WIRING (Fig. C)
9. Connect one (1) wire from the electric valve to
the positive (+) battery terminal, alternator, etc.
Always protect this circuit with a three (3) amp
fuse (not included).
10. Connect the other wire of the electric sole-
noid valve to the horn switch (not included).
11. Connect the horn switch’s other terminal to
ground, any metal body bolt that is clean of
paint and rust.
