MOUNTING

1. Locate the desired area you wish to mount the Dominator Horn. For best results, the front of the horn should be

unobstructed so that the horn’s sound can project straight ahead. Use the horn’s gasket as a template, mark hole

locations and drill to size. (See Fig. A.)

2. Mark the wire hole location if the horn’s wire is going to pass through the mounting surface and drill to size. (See Fig. C)

IMPORTANT: Make sure the hole is free of

any burrs that could cut into the horn’s

wire. For roof mount mounting, to prevent

water leaks, it is recommended that silicon

or a waterproof sealer be placed on the

wire at the point of entry into the roof.

3. Secure the horn using the hardware

provided. Tighten screws evenly to

prevent damage to the horn. (See Fig.

A.) IMPORTANT: Be sure to use the

rubber gasket to protect against water

leaks.

4. Push the front bracket forward until it is

tight. Use the bracket as a template,

mark hole location and drill to size. (See

Fig. B).

5. Secure the front trumpet bracket to the

location using the hardware provided.

Tighten screw evenly. IMPORTANT: Be

sure to use the rubber gasket to protect

against water leaks.
