Before you begin the installation
• Read the INSTRUCTIONS!
• Always use a multi-meter when verifying
vehicle wiring.
• Before mounting the product, verify with
the customer the desired location for the
valet switch and LED.
• Protect the vehicle by using fender covers.
• Always look before drilling. Make sure you
will not cause damage to vehicle hoses,
electrical looms or physical damage to
vehicle.
• Set the Polarity Jumpers inside the main
unit. (see Jumper Settings)
Mounting System Module
Mount the system module under the dash
where it will be difficult for a potential thief
to locate the module, and away from moving
parts such as brake pedals, etc. Route the
antenna wire away from wire looms,
computer modules and metallic objects for
better range.
Mounting Siren
Mount the siren in a suitable place under the
hood, away from hot and moving engine
parts such as manifolds, fan belts, etc. Make
sure the siren cannot be accessed from
underneath the vehicle or through the grill.
Face the siren down so that water cannot
accumulate inside the siren bell. Protect
wires running through the firewall using
either tape or split loom tubing. If a new hole
is needed, protect the wire from chaffing by
installing a proper size grommet.
Mounting Shock Sensor
Secure the shock sensor to the steering
column, thick wire harness or a dash brace,
using a wire tie. Make sure that the
adjustment screw is accessible for later
testing and adjustment.
16-Pin Main Harness:
• BROWN WIRE - Siren wire output (+) 3A.
Connect to the siren’s red wire. Connect
the siren’s black wire to ground.
• BLACK WIRE - Ground input (-). Connect
to a solid chassis ground that is clean and
free of paint or dirt.
• ORANGE WIRE - Armed Output (-)
500mA. Connect to a relay for optional
circuit defeat (See installation diagrams).The
ORANGE wire provides a ground when the
unit is armed to activate a fuel pump disable
relay or other device (i.e. window control
module, etc.).
• EMPTY - not used.
• YELLOW WIRE - +12V Ignition input.
Connect to a main ignition wire at the
ignition switch harness. This wire shows
+12V when the ignition is on and while
cranking. The voltage must not drop when
the car is starting.
• BROWN/WHITE WIRE - Horn output (-)
500mA. Connect to an optional relay to
honk the vehicle’s horn when the alarm is
triggered.
• BLACK/YELLOW WIRE - Auxiliary 3
output (-) 500mA. Connect to a relay for an
optional feature such as headlight activation,
etc. This output may be programmed for
momentary, timed, or latched operation.
