Installation Instructions
Before you begin the installation
• Read the INSTRUCTIONS!
• Always use a multi-meter verify wiring.
• Before mounting the product, verify
with the customer the desired location for
the valet switch and LED.
• Protect the vehicle using fender covers.
• Always look before drilling. Make sure
you will not cause damage to vehicle
hoses, electrical looms or physical
damage to vehicle.
Mounting System Module
Mount the system module under the
dash where it will be difficult for a thief
to locate, and away from moving parts.
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 engine compartment using split loom
tubing. If a new hole is needed, protect the
wire from chaffing by installing a grommet.
14-Pin Main Harness:
• WHITE WIRE - Parking Light output
(+/-) 10A relay. Connect to the vehicle's
parking light wire. If the circuit exceeds 10
amps a relay is required. For vehicle's with
independent left and right parking light
circuits, the wires must be connected
using diodes to keep the circuits separate.
For negative (-) trigger vehicles, move the

internal jumper next to the relay as shown
on the back page diagram. NOTE: Do not
connect to the headlight circuit.
• BLACK WIRE - Ground input (-).
Connect to a solid chassis ground that is
clean and free of paint or dirt.
• RED WIRE - +12V Battery input.
Connect the red fused wire on the main
harness to a constant +12V source. This
wire should be at least a 15 amp supply.
• BROWN WIRE - Siren wire output (+)
2A. Connect to the siren's red wire.
Connect the siren's black wire to ground.
• GRAY WIRE - Auxiliary 1 output (-)
500mA. Connect to a relay for an optional
feature such as trunk release, etc.
• WHITE/BLUE WIRE - Auxiliary 2 output
(-) 500mA. Connect to a relay or module
for an optional feature such as power
window roll-up, etc.
• ORANGE WIRE - Armed Output (-)
500mA. Connect to a relay for optional
starter defeat (See wiring diagram). The
ORANGE wire provides a ground when
armed to activate a starter disable relay or
other device (i.e. window module, etc.).
• BLACK/WHITE WIRE - Dome Light
output (-) 500mA. Connect to an optional
relay to activate the vehicle's dome light.
• WHITE/GREEN WIRE - Passenger
Unlock output (-) 500mA. Connect to a
relay to unlock the passenger doors when
wired for Driver Priority Unlocking.
• BLUE WIRE - Trunk/Hood trigger (-).
Connect the Blue wire to the trunk
and/or optional hood pin switches. The
switch must provide ground when opened.
• GREEN WIRE - Negative door trigger (-).
Connect to the door switch circuit wire that
