PROFESSIONALINSTALLATION
STRONGLYRECOMMENDED
Installation Precautions:
Roll down window to avoid locking keys in vehicle
during installation
Avoid mounting components or routing wires near
hot surfaces
Avoid mounting components or routing wires near
moving parts
Tape or loom wires under hood for protection and
appearance
Technical Support [phone]
or go to
http://techservices.codesystems.com
Use a Digital Multi Meter for testing and verifying
circuits. DO NOT USE ATEST LIGHT, OR
"COMPUTER SAFE PROBE" as these can set off air
bags or damage vehicle computers.
Use grommets when routing wires through metal
surfaces

LED Port
The LED included in the kit will serve as a visual indicator of the alarm’s status. It
should be installed in the dash, located where it can be easily seen from outside
the vehicle, yet not be distracting to the driver. Once a location has been
selected, check behind the panel for wire routing access, and to confirm the drill
will not damage any existing components as it passes through the panel. Drill a
1/4" hole, and pass the red and blue wires from the LED through the hole, from
the front of the panel. Firmly press the body of LED into the hole until fully seated.
Additional Ports
Programming / Valet Button Port
Select a mounting location that is within reach of the ignition switch, as this
switch in combination with the ignition switch, will be used to program the certain
features of the system. It is suggested that the switch be mounted to the lower
dash panel in the driver’s area within reach of the driver.
