H1/3 WHITE/BLUE (+) TRUNK RELEASE, SENSOR SHUNT INPUT
This input is used to bypass sensor inputs when the trunk is opened using the factory transmitter. Connect this
wire to the (+) trunk release output of the factory keyless entry system or trunk release relay. When the system
receives a (+) input on this wire, Zones 2 and 4 are bypassed for three seconds. If ground is applied to the H1/6
BLUE wire during that three-second period, Zones 2 and 4 will remain bypassed until the ground input is removed.
This means that when the trunk is opened with the factory transmitter, the only triggers that remain active while
the trunk is open are the doors. Five seconds after the trunk is closed, the bypassed zones will become active again.
NOTE: This connection is not required with most Class II databus systems.
H1/4 BROWN/BLACK (-) 200 mA HORN HONK OUTPUT
This wire supplies a (-) 200 mA output that can be used to honk the vehicle’s horn. It provides a pulsed output
when the security system is in the triggered sequence or in Panic Mode. In most vehicles with (-) horn circuits,
this wire can control the vehicle’s horn without adding a relay. If the vehicle has a (+) horn circuit, an optional
relay must be used to interface with the horn circuit.
IMPORTANT! Never use this wire to drive anything except a relay or a low-current input! This tran-
sistorized output can only supply (-) 200 mA. Connecting directly to a high current device will cause
the module to fail.
H1/5 YELLOW/BLACK DATABUS CONNECTION
The databus wire is a wire that connects to the vehicle’s network of control modules and allows communication
throughout the vehicle. This wire is located at Pin #2 of the diagnostic plug or the On-Board Diagnostic II (OBD
II) connector located under the dash in the driver’s compartment. (See diagram below.) This wire carries a low
voltage data signal and CANNOT be tested. Connect this wire to the databus signal wire in the vehicle. On GM
vehicles, the data plug wire is usually purple. On Jeep Grand Cherokees, the data plug wire is usually yellow/black
or yellow/purple. The databus connector is usually located to the left of the steering column under the driver’s
side dash.
IMPORTANT! The databus connection wire should only be connected to the databus signal wire in
the vehicle. Do not connect the H1/5 YELLOW/BLACK wire to any other wire!
