Wiring Description

14-Pin Main Harness

Pin 1 - Red: Main Power (+12v) input [15A fuse]

Connect to constant +12v. A clean source of power is essential. This connection can be made at either the battery or at

the constant power supply wire to the ignition switch.

If this wire needs to be lengthened, use the appropriate wire gauge to avoid a drop in current and be sure to install a fuse

near the connection. Do not remove or bypass the fuse holder included on the wire harness.

Pin 2 - Brown: Siren (+12v) output.

Connect to the Red siren wire. Connect the Black siren wire to chassis ground.

Pin 3 - White: Parking Light (+12v) output.

Connect to positive light circuit. For vehicles that have independent left and right parking light circuits, the parking light

wires must be connected using diodes to keep the circuits separate.

Pin 4 - Yellow/Blue: Auxiliary 2 (-) output.

Provides a negative (-) output which can be programmed for validity, latched, or 30 second timed operation.

Pin 5 - Blue/White: Passenger/Priority Unlock (-) output.

Provides a negative output (-) while the alarm is disarmed to unlock the vehicle's passenger door. Connect to an optional

relay. (See Door Lock Diagrams - Page 13)

Pin 6 - Brown/White: Horn Honk (-) output.

Connect to a relay to honk the vehicle horn.

Pin 7 - Orange: Optional Circuit Defeat (-) output.

Provides a negative output to disable the vehicle's ignition or fuel pump circuits. Connect to an optional relay as shown

This output is programmable for either normally open or normally closed operation. (See Programming on page 10)

Pin 8 - Blue: Hood/Trunk Trigger (-) input.

Connect to a negative output from the hood and trunk pin switches.

Pin 9 - Black/White: Dome Light (-) output.

Illuminated Entry/Exit output. Provides a negative (-) output to turn on the vehicle's dome light when the system is

disarmed. Normally, this wire can be connected to the door switch circuit. (See Dome Light Diagrams - Page 15)

Pin 10 - Yellow/White: Auxiliary (-) output.

Provides a negative (-) momentary output.

Pin 11 - Yellow: Ignition input (+12v) input.

Connect to a source that maintains +12v when the ignition key is in both the "on" and "start" positions.

Pin 12 - Black: Ground.

Connect to a solid chassis ground. Be sure to use a ring connector of proper size. Scrape away the paint at the grounding

point.

Pin 13 - Violet: Door Trigger (+12v) input

Connect to positive door switch circuit. This circuit, commonly found in Ford vehicles, will show (+12v) when the door is

open.

Pin 14 - Green: Door Trigger (-) input

Connect to negative door switch circuit. This circuit will show (-) when the door is open.

5-Pin Door Lock Harness

Pin 1 - White/Black: Lock 87A (Normally closed)

Pin 2 - Green/Black: Lock 30 (Common)

Pin 3 - Blue/Black: Unlock 30 (Common)

Pin 4 - Brown/Black: Unlock 87A (Normally closed)

Pin 5 - Violet/Black: Lock/Unlock 87 (Normally open) [10A Fuse]

On-Board Starter Defeat Wiring
