5-Pin Harness
Pin 1 ORANGE WIRE: Accessory Output for heater/air conditioner(negative) to activate external relay
Pin 2 YELLOW WIRE: Ignition 1 output (negative) to activate external relay.
Pin 3 VIOLET WIRE: Starter Output (negative) to activate external relay
pin 4 BROWN WIRE: Ignition 2 output (negative) to activate external relay.
pin 5 RED WIRE: +12V Power to external relays.

16-Pin Main Harness

Pin 1 BROWN/WHITE: Horn Output (-) 500 mA. Connect to a relay to activate the vehicle's horn when the
alarm is triggered. This wire may instead be programmed as an ignition 3 relay trigger.
Pin 2 BLACK/GRAY WIRE: Tach Input. (required for all manual transmission installations) Connect
to the vehicle's tach wire or a fuel injector wire if the tachless mode does not provide satisfactory
operation.
Pin 3 BROWN: Siren Output (+) 3A. The Brown wire must connect to the siren's red wire. The Black siren
wire must be grounded (optional).
Pin 4 GREEN WIRE: Negative Door Input (-). Connect to the door switch circuit wire that shows ground
when the door is open.
Pin 5 VIOLET WIRE: Positive Door 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 6 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 and while cranking the starter. The
voltage must not drop when the car is starting.
Pin 7 WHITE/BLACK WIRE: Hood Pin Input (-). Connect the to the hood pin switch. The switch must
provide a ground output when switch is opened.
Pin 8 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 9 VIOLET/WHITE WIRE: Factory Rearm Output (-) 500 mA. The White/violet wire provides a ground
output on remote start shutdown to rearm a factory security system. Connect to the wire that requires
a ground pulse to rearm the factory security system.
Pin 10 WHITE/VIOLET WIRE: Factory Disarm Output (-) 500 mA. The Violet/white wire provides a ground
output on disarming and before remote starting to disarm a factory security system. Connect to the
wire that requires a ground pulse to disarm the factory security system.
Pin 11 BLUE/ORANGE WIRE: Ground When Running Output (-) 500 mA. Connect to an optional factory
security bypass module if required.
Pin 12 ORANGE WIRE: Anti-Grind Output (-) 500 mA. The Orange wire provides a ground output to activate
a relay for anti-grind protection.
Pin 13 GRAY WIRE: Auxiliary 1 Output (-) 500 mA. Connect to a relay for an optional feature such as trunk
release, etc. This output may be programmed for momentary, timed, or latched operation.
Pin 14 GREEN/WHITE WIRE: Brake Input (+). Connect to the wire that shows +12V when pressing the
brake. The Green/white wire is a safety shutdown wire that must be connected.
Pin 15 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
