MOUNTING
Identify a suitable area for mounting, preferably an unobstructed sheet-metal surface like the frame or body of
the vehicle so as to provide a firm platform which will help protect the horn from damage due to excessive
shaking. Do not attach the horn to any plastic or other flexible material.
Using the bracket as a guide estimate and mark the positions for the holes and then perforate to size using a
drill.
Use the provided mounting hardware to fasten the horn.
AIR LINE INSTALLATION
On one side of the included
¼” OD air line, attach the compression nut and force the air line upon the male
inlet fitting which is found on the electric solenoid valve.
Pass the brass nut through the inlet fitting and fasten.
Take the air line’s other side and place the compression nut of the air tank fitting on it. Force the air line onto
the male fitting of the tank and then fasten the compression nut.
WARNING
: Avoid tying the brass nut too
tight.
ELECTRICAL CONNECTIONS
Wire one of the solenoid valve’s leads to the positive (+) terminal of the battery or alternator.
WARNING
: We
highly recommend that you use a 10A fuse (not provided) to assure that the circuit remains safe and will not
be damaged by excess current.
Wire the other lead of the solenoid valve to one of the terminals on the horn button.
Ground the other terminal on the horn button by wiring it to bare metal.
