The functions of all the wires that are used in the primary harness are outlined in this section.
This wire supplies (-) ground as long as the system is armed. This output ceases as soon as the system is dis-
armed. This wire can be used to turn on an optional sensor or to control an optional accessory, such as a window
module or pager.

This wire should be connected to the (+) parking light wire. This output is protected with a 10 amp fuse. Never
increase the value of the light flash fuse. If more current is required, use an external relay.
NOTE: When connecting this wire to a (-) parking light wire, a relay is required. See the following
diagram for the relay application.
This wire provides a (-) 200 mA output whenever the transmitter code controlling Channel 3 is received. This
output will continue as long as that transmission is received. Use for options such as 551T Valet Start system,
529T or 530T power window controllers, etc.
IMPORTANT! Never use this wire to drive anything except a relay or a low-current input! The transistorized output can only provide 200 mA of current, and connecting directly to a solenoid, motor,
or other high-current device will cause it to fail.
Connect this wire to the optional domelight supervision relay as shown in the following diagram.

H1/3 WHITE/BLUE (-) channel 3 validity output
H1/2 WHITE (+) light flash output

IMPORTANT! This output is only intended to drive a relay. It cannot be connected directly to the
domelight circuit, as the output cannot support the current draw of one or more light bulbs.
Most vehicles use negative door trigger circuits. Connect the green wire to a wire which shows ground when any
door is opened. In vehicles with factory delays on the domelight circuit, there is usually a wire that is unaffected
by the delay circuitry. This wire will report Zone 3.
This input will respond to a negative input with an instant trigger. It is ideal for hood and trunk pins and will
report on Zone 1. It can also be used with 506T Glass Breakage Sensor, as well as other DEI single stage sensors.
The H1/6 BLUE instant trigger wire can be used to shunt sensors during operation, using the auxiliary channels.
When any of the auxiliary channels are transmitted, the H1/6 BLUE wire monitors for a ground. If a ground is
detected within 5 seconds of transmission, the sensors and the instant trigger input on the BLUE wire will be
shunted until 5 seconds after the ground is removed. This allows the customer to access the trunk, remote start
the vehicle or roll the windows down without first disarming the alarm. (See Bypassing Sensor Inputs section of
this guide.)
H1/6 BLUE (-) instant trigger, zone 1
H1/5 GREEN (-) door trigger input, zone 3
