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 A TEST LIGHT, OR
"COMPUTER SAFE PROBE" as these can set off air
bags or damage vehicle computers.
Use grommets when routing wires through metal
surfaces
