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!
H1/6 BLUE (-) INSTANT TRIGGER, ZONE 1
This input will respond to a negative input with an instant trigger. It is ideal for hood and trunk pins or vehi-
cles without factory Content Theft Deterrent (CTD). Vehicles without CTD may require trunk pins or need to be
hard-wired to the alarm. (A trunk pin wire may need to be added if the vehicle does not already have a factory
trunk pin.) The H1/6 BLUE wire will report on Zone 1.
NOTE: Factory CTD systems in Bonnevilles, Auroras and LeSabres do not monitor the trunk pin wire.
For Level I security mode, the H1/6 BLUE wire must be hard-wired to the vehicle’s factory trunk pin
wire. This step is not required if Level II security mode is selected.
