Red & Green 2 Pin White Connector : DOOR LOCK OUTPUTS
These wires will provide either a pulsed ground output to the factory door lock control relay, or a pulsed +
12 volt output to the factory door lock control relay. In either case, the maximum current draw through
these outputs must not exceed 300 mA.
3 Wire Ground Switched Door Locks
In this application, the red wire provides a ground pulse during arming, or the pulsed ground lock output.
Connect the red wire to the wire that provides a low current ground signal from the factory door lock switch
to the factory door lock control relay.
The green wire provides a ground pulse during disarming, or the pulsed ground unlock output. Connect the
green wire to the wire that provides a low current ground signal from the factory door unlock switch to the
factory door lock control relay.
3 Wire Positive Switched Door Locks
In this application, the red wire provides a positive pulse during disarming, or the pulsed + 12 volt unlock
output. Connect the red wire to the wire that provides a low current positive signal from the factory door
unlock switch to the factory door lock control relay.
The green wire provides a positive pulse during arming, or the pulsed + 12 volt lock output. Connect the
green wire to the wire that provides a low current positive signal from the factory door lock switch to the
factory door lock 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
Antenna Wire : Be sure to extend the thin black antenna wire to it’s full length, and cable tie into place
where it cannot be damaged. Avoid wrapping this wire around major, high current wire looms.
Adjusting the Shock Sensor :
If used, 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.
CAUTION : 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.
WARNING ! 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.
