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 Relay Output (+/–) 7A. Connect to the wire that activates the
vehicle’s dome light, usually the door pin switch wire. NOTE: The dome light output may usually connect
to the same wire used for the door trigger input (See GREEN or VIOLET door trigger wires).
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.
5-Pin Door Lock Harness
Pin 1 WHITE WIRE: Lock Relay Pin 87a (Normally Closed).
Pin 2 GREEN WIRE: Lock Relay Pin 30 (Common).
Pin 3 BLUE WIRE: Unlock Relay Pin 30 (Common).
Pin 4 BROWN WIRE: Unlock Relay Pin 87a (Normally Closed).
Pin 5 VIOLET WIRE: Lock/Unlock Relays Pin 87 (Normally Open) [10A Fuse].
