System Wiring
14-Pin Main Harness
Pin 1
RED WIRE
: +12V Battery Input (15A Fuse). The RED wire must be connected to a clean source of
cont12V power.
Pin 2
WHITE WIRE
: Parking Light Output (+/-) relay. Connect the White wire to the circuit that shows
+12V or ground only when the parking lights are on and set the internal parking light relay jumper to
the proper polarity. For parking light circuits exceeding 10 amps, a relay is required. For vehicle’s with
independent left and right parking light circuits, diodes must be installed to keep the circuits separate.
NOTE: Do not connect the WHITE wire to the vehicle’s headlight circuit.
Pin 3
BROWN WIRE
: Siren Output (+) 3A. The BROWN wire must connect to the siren’s red wire. The
BLACK siren wire must be grounded.
Pin 4
BLUE/WHITE:
Passenger Unlock output (-) 500mA. Connect to an optional relay to unlock the
passenger doors for two-stage unlock (see Two Stage Door Lock Diagrams).
Pin 5
WHITE/RED WIRE
: Auxiliary 2 Output (-) 500mA. Connect to a relay or module for an optional
feature such as power window activation or remote start, etc.
Pin 6
ORANGE WIRE
: Armed Output (-) 500mA. The ORANGE wire provides a ground output while armed
to activate an optional starter defeat relay or other device such as a power window control module.
Pin 7
BROWN/WHITE WIRE
: Horn Output (-) 500mA. Connect to an optional relay to activate the
vehicle’s horn when the alarm is triggered.
Pin 8
BLACK/WHITE WIRE
: Dome Light Output (-) 500mA. Connect to an optional relay for dome light
activation.(See GREEN and VIOLET door trigger wires).
NOTE: MUST USE RELAY
Pin 9
BLUE WIRE
: Trunk/Hood trigger Input (-). Connect the BLUE wire to the trunk and/or optional hood
pin switches. The switch must provide a ground output when opened.
Pin 10
GRAY WIRE
: Auxiliary 1 Output (-) 500mA. Connect to a relay or module for an optional feature
such as trunk release, etc.
Pin 11
YELLOW WIRE
: +12V Ignition Input. The YELLOW wire must connect to a main ignition wire at the
ignition harness. This wire must show +12V when the ignition is on.
Pin 12
BLACK WIRE
: Ground Input (-). The BLACK wire must connect to a solid chassis ground. Clean away
any paint or dirt to insure the best possible ground.
Pin 13
VIOLET WIRE
: Positive door trigger Input (+). Connect to the door switch circuit wire that shows
+12V when the door is open. This type of door circuit is usually found on Ford vehicles.
Pin 14
GREEN WIRE
: Negative door trigger Input (-). Connect to the door switch circuit wire that shows
ground when the door is open.
