The red wire provides a positive pulse during disarming, or the drivers door pulsed positive unlock output. Connect this
wire to the drivers door unlock relay that requires a low current positive signal to unlock only the drivers door. If the vehicle
does not have a separate drivers door relay, one will have to be added. Locate the drivers door unlock motor wire and cut it at
a convenient location to allow wiring of an optional relay. Connect the door side of the cut wire to terminal 30 of the optional relay
added. Connect the vehicle side of the cut wire to terminal 87a of the optional relay added. Connect the red wire of the 3 pin
harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay added to chassis ground. Most
vehicles door lock/unlock motor legs rest at ground, and 12 volts to the door lock/unlock motor legs for operation, if this
is the case in the vehicle you are working on, connect the remaining terminal, 87, to a fused + 12 volt source. In the rare instance
that the vehicle door lock/unlock motor legs rest at + 12 volts and switches ground to the door lock/unlock motors, connect he
remaining terminal, 87, to chassis ground.
The Red/Black wire provides a pulse ground output when the unlock button of the transmitter is pressed a second time after disarming.
Because the vehicle you are working on requires a positive pulse from the factory door lock switch to the factory door lock control relay,
you will have to add a relay to invert the output polarity of this wire. Connect the Red/Black wire to terminal 86 of the optional added
relay. Connect terminal 85 & 87 to a fuse + 12 volt source. Connect terminal 30 to the low current door unlock wire from the factory
door switch to the door unlock control relay.
Resistive Circuits, As Well As 4 Wire Polarity Reversal and 5 Wire Alternating 12 Volt
Door Lock Control Circuits
These applications require the use of additional components which may include relays, fixed resistors, or for convenience, the
AS 9159 Door Lock Interface. Refer to the AUDIOVOX Door Lock Wiring Supplement and or the Audiovox fax back service for
information on your particular vehicle for properly connecting to these types of circuits.
COMPLETING THE INSTALLATION
Adjusting the Shock Sensor : The sensitivity of the pre - detect circuit is automatically set 30% less sensitive than the full
trigger circuit.
Using a small screwdriver, gently turn the adjustment screw fully counterclockwise. (DO NOT over turn this screw. Maximum
rotation for this adjustment is 270°). Close the hood and trunk lids, and arm the alarm. Wait 6 seconds for the accessories trigger
zone to stabilize, then firmly strike the rear bumper with the side of a closed fist considering the amount of force required to break
a window.
WARNING : Never perform this test on the vehicle’s glass, as you may break the window.
Turn the adjustment screw clockwise (increasing sensitivity) about ¼ turn and re - test. Repeat this procedure until the alarm
sounds. Ultimately, one firm strike to the rear bumper will cause the alarm to emit pre - detect warning tones.
CAUTION ! Setting the sensitivity too high can cause false alarms due to noise vibrations from passing trucks and heavy equipment.
To decrease sensitivity, turn the adjustment screw counter clockwise.
Wire Dressing : Always wrap the alarm wires in convoluted tubing, or with a spiral wrap of electrical tape. Secure these looms
along the routing using cable ties. This will ensure that the alarm wires are not damaged by falling onto hot or sharp moving
surfaces in the vehicle.
Operation : Take a few moments to check off the appropriate option boxes in the owner’s manual, and to fully explain the
operation of the system to your customer.
