Mounting Components

Main Unit

The main unit should be mounted in the interior of the vehicle. Do not mount the main unit
in the engine compartment. For maximum security, avoid mounting the main unit where it
will be easily accessible to a thief.
If you are mounting the unit under the dash board, be sure to mount the unit as high as
possible and in a location where it will not interfere with the operation of the pedals.
Be sure to extend the antenna as high as possible so that optimum range can be achieved.
Before securing the unit, be sure that you have made all of the necessary switch and jumper
selections and perform a thorough function test of the system.
The case of the MS850 is designed to be mounted using screws, or secured using wire ties
through the wire tie mounting tabs located on the unit.

Siren

Mount the siren facing downward and away from sources of heat and face the opening
downward to prevent water from collecting inside the housing. Be sure that the wires are
not easily accessible from underneath the vehicle.
For maximum security, it is best to disguise all under hood system wires with factory style
split loom tubing so that they cannot be easily identified by a thief.
Run all wires from the engine compartment into the interior of the vehicle through a
grommet.

Shock Sensor

The dual stage, electronic shock sensor, included with the system, is designed to be
mounted in the interior of the vehicle using a tie wrap or double sided tape. Be sure to avoid
mounting the sensor to sources of strong electrical interference such as cellular phone
transceivers or the vehicle's engine computer.
Suggested mounting locations are an air conditioning duct, or a dashboard or center
console support brace.

Override Switch

Mount the Override Switch in a location near the driver where it is easily accessible but not
plainly visible. Plug the blue override switch connector into the blue 2-pin socket on the
main unit.
Be sure that the switch cannot accidentally be pressed or damaged by movement of
passengers or contents within the vehicle.

LED Status Indicator

Mount the status LED so that it is visible from both sides of the vehicle. Plug the white
LED connector into white 2-pin socket on the Main Unit.
