BLACK (-) CHASSIS GROUND
This wire is the main unit’s source of ground. DO NOT connect this wire to any factory ground points; they
can cause noise and/or current loss which can affect system performance. Ground the main unit and any
accessories to the same point in the vehicle, (preferably the kick panel). Scrape away any paint and use a
factory bolt or make your own ground with a self-tapping screw and a star washer
[Required connection for both configurations]
RED (+) 12V CONSTANT INPUT
This wire supplies power to the main units’ micro-controller. Remove the supplied fuse before connecting to
the positive terminal of the battery or a constant +12V supply to the ignition switch.
Note: Always use a fuse within 12 inches of the point you obtain (+)12V. Do not use the 15A fuse in the
harness for this purpose. This fuse protects the module.
[Required connection for both configurations]
WHITE/BLACK LIGHT FLASH ISOLATION WIRE (PIN 87a of onboard relay)
This wire is a parking light flash input from the vehicle light switch that connects to pin 87a of the on-board
light flash relay. It is used for vehicles requiring light switch isolation during light flash output. For vehicles
with multiplex light circuits that require switch isolation, the on-board light flash fuse can be replaced with
the specified resistor value (paying attention to the circuit polarity). See diagram below for wiring information.

Nuisance Prevention Circuitry (NPC)
NPC monitors all alarm zones and, if any are triggered three times within an hour, bypasses them until
corrected. If a point of entry (trunk, hood, or door) is left open following a forced entry, it is bypassed. It becomes active again only after being closed. Bypassed sensors automatically reset after one hour and after
the vehicle is driven. Disarming then re-arming the alarm does not reset bypassed sensors.
Long Term Event History
The system stores the last two full triggers in memory. These are not erasable. Each time the unit sees a full
trigger, the older of the two triggers in memory is replaced by the new trigger. To access long term event
history:
1. With the ignition Off, press and hold the Valet button
2. Turn the ignition On.
3. Release the Valet button.
4. Within 5 seconds, press and release the Valet button. The status LED flashes in groups indicating the
last two zones that triggered the unit for 1 minute or until the ignition is turned off. Refer to table of
zones.
Note: The Warn Away triggers are not stored to memory and are not reported.
Table of Zones
When arming the system with an active zone or when the system has been triggered, the LED will flash to
indicate the zone that is active or has been triggered. A zone is represented by the number of LED flashes
used by the system to identify a particular type of input.

Rapid Resume Logic
This system will store its current state to non-volatile memory. If power is lost and then reconnected the system will recall the stored state from memory. This means if the unit is in valet mode and the battery is disconnected for any reason, such as servicing the vehicle, when the battery is reconnected the system will still be
in valet mode. This applies to all states of the system including arm, disarm and valet mode.
• Was the onboard shock sensor adjusted before the brain was mounted? If so re-adjust the sensor.
• Has the onboard shock sensor been turned down all the way? If so re-adjust the sensor
• Has the NPC® system been triggered? If so, you hear 5 chirps when disarming. To check this,
turn the ignition key on and off to clear the NPC® memory, and then retest the shock sensor. For a
detailed description of NPC®, see Nuisance Prevention Circuitry section of this guide.
Door input does not immediately trigger full alarm. Instead, sounds are heard for the first 3 seconds:
• That’s how the progressive two-stage door input works! This is a feature of this system even if the
door is instantly closed again, the progression from pretrigger sounds to full trigger sounds continues.
Closing the door triggers the system, but opening the door does not:
• Have you correctly identified the type of door switch system? This happens often when the wrong
door input has been used.
System does not passively arm until it is remotely armed and then disarmed:
• Is passive arming programmed ON?
• Are the door inputs connected? Is the blue or gray wire connected to the door trigger wire in the
vehicle?
• Either the green or the violet should be used instead.
Door input does not respond with the progressive trigger, but with immediate full alarm:
• Does the Status LED indicate that the trigger was caused by the shock sensor? (See Table of Zones
section of this guide.) The shock sensor, if set to extreme sensitivity, may be detecting the door unlatching before the door switch sends its signal. Reducing the sensitivity can solve this problem.
Door locks operate backwards.
• This unit has easily-reversed lock/unlock outputs. Recheck wire connections to see if you have
