1.
Use a Volt / Ohm meter to test all wires.
Do not use a test light.
2.
Good power and ground connections are essential for proper operation. Ground the alarm
as close to the alarm main unit as possible.
3. 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.
4.
When adding optional accessories such as door locks, window modules, etc., be sure to
fuse each additional accessory power lead separately from the main power source. This
will insure that the security system power is retained in the event that an accessory
malfunctions.
5.
Avoid extending the system’s wires, the supplied wiring harnesses provide sufficient length
to connect to the required vehicle circuits. If a wire must be extended, be sure to use the
appropriate gauge wire in order to avoid a drop in current. Always use wire that is at least
the same gauge as the wire you are extending.
6.
Never bypass the fuses included in the MS850 wiring harness. They are necessary safety
items designed to protect both the system and the vehicle.
7.
Be sure to perform a full function test of all of the systems components to verify proper
operation. Also, be sure to check all of the vehicle’s operating systems before and after the
installation.
8.
For maximum security, disguise all system wires with black electrical tape and split loom
tubing to prevent a thief from being able to identify the system wiring.
