Before You Begin Be sure to read the manual thoroughly before beginning the installation to ensure a proper understanding of the MS850 and its functions. Verify system contents: Main Unit Two 2-Button Remote Transmitters Siren Electonic Shock Sensor Harnesses • 14-Pin main harness •...
Installation Tips Use a Volt / Ohm meter to test all wires. Do not use a test light. Good power and ground connections are essential for proper operation. Ground the alarm as close to the alarm main unit as possible. Route all wires from the engine compartment to the interior of the vehicle through a grommet and use electrical tape and split loom tubing for protection.
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.
