Mounting the Control Unit
The control unit must only be mounted in the interior of the vehicle. Do not mount the main unit in
the engine compartment. Choose a mounting location that will not be easily accessible to a thief, and
will not interfere with the operation of any vehicle components such as foot pedals, steering column,
air vents, seat rails, etc.
Do not mount the control unit until after setting the internal jumpers and performing a complete op-
eration check of the system. After installation is complete and performance verified, the control unit
can be easily mounted using wire ties through the mounting tabs on the bottom of the unit.
Mounting the Siren
Choose a siren mounting location that is away from heat sources such as exhaust manifolds, and
where it cannot be easily accessed from underneath the vehicle. Be sure to face the siren downward
to prevent the collection of water in the siren’s housing.
Always route all wires from the engine compartment into the interior of the vehicle through a proper
grommet.
Mounting the Shock Sensor
Choose a suitable interior mounting location for the shock sensor that provides ample coverage of the
vehicle. Keep the sensor away from the vehicle’s ECM or other sources of electrical interference. Sug-
gested mounting locations include air conditioning ducts, dashboard braces, or center console sup-
ports.
During proper operation, the shock sensor will detect impacts to the vehicle only and will not usually
be triggered by slow rocking movements of the vehicle like those caused by wind.
