MOUNTING

1. Select a mounting location at the rear of the vehicle that will
permit the alarm’s sound to be unobstructed. Also, the
mounting location should provide protection from wet
conditions and possible impact to the alarm. The alarm‘s
front grill should be mounted facing the targeted hazard
area of the vehicle. Mount the alarm at an approximate
height of four (4) feet above ground level.

2. The alarm‘s L-type mounting configuration provides an easy
mounting and installation. Use the alarm’s mounting bracket
as template, mark one (1) hole location on each side of the
alarm and drill to size 5/16”.

3. Secure the alarm to the vehicle using the hardware provided.

4. The RED WIRE is spliced to the power wire of either the reverse
switch or back-up light using the splice connector provided. The
back-up light has the clear lens. To protect the vehicle from fire,
always use the in-line (1) amp fuse connected to the alarm’s red
wire. Push the splice connector onto the reverse switch wire or
back-up light wire. Insert the alarm’s red wire into the splice
connector. Using pliers press down the protruding metal tab into
both wires. Rotate the cover until it snaps closed.

5. The BLACK WIRE is connected to body ground. Secure the
terminal at the end of the alarm’s black wire by drilling a 1/8”
hole on any clean body surface. Use the screw provided to
secure the terminal. Be sure to clean the ground surface to be

6. free of rust and paint to assure a good ground connection with

the terminal.

6. NOTE: The back-up alarm must be wired as above Fig. A. If the
polarity is reversed, the alarm will not operate. This alarm must
have a good power connection and ground to work reliably. Use
18-gauge wire (minimum) to lengthen wire leads if required.
Make sure that all wires are secured and inspect to ensure that
they will not interfere with vehicles operation. Always make sure
that any wiring is in accordance with the vehicle manufacturer’s
recommendations.
