5 Wire Alternating Door Lock Circuits :
In this application, it is necessary to cut the existing door lock by - pass wires. These wires run from the master door
lock switch to the slave door lock switch, and then on to the door lock motors.
Cut the existing lock wire, and connect the yellow wire to the slave switch or motor side of the cut wire. Connect the
green wire to the master switch side of the cut wire.
Cut the existing unlock wire, and connect the white wire to the slave switch or motor side of the cut wire. Connect the
blue wire to the master switch side of the cut wire.
The orange and blue w/ white stripe wires must be connected to a fused + 12 VDC battery source.
Refer to the door lock wiring supplement for proper connection of these wires into the various locking circuits
available in current vehicles.
2 STEP UNLOCK OPERATION
6 Pin Door Lock Output Connector :
When wiring for 2 step unlock operation, you must connect the outputs of the on board unlock relay to the driver’s
door lock motor. Wire these outputs as follows;
Orange = N.O. Relay Contact to + 12 VDC Battery
Dark Blue = N.C. Relay Contact to Motor leg switch side
White = Common Relay Contact to Motor leg motor side
Wire the transistorized negative “ all doors unlock “ output directly to the negative unlock wire from the door lock
switch in vehicles with 3 wire ground switched circuits.
In vehicles with 3 wire positive or 5 wire alternating switched circuits, you must add a 30 Amp automotive relay to
provide the “ all doors unlock “ feature.
Red w/ Black & Green w/ Black 2 Pin Red Connector : 2 Step Unlock Connector
The green w/ black tracer wire provides a 300 mA ground pulse output for the all doors unlock signal, and can be
connected to the negative door unlock wire in 3 wire negative switched vehicles.
The red w/ black trace wire provides a low current (300 mA) + 12 VDC source for those applications that require a
relay for the all doors unlock feature. This wire should be connected to the relay coil only. A separate +12 VDC
source must be used for the high current relay contacts.
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 : 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 very firm strike to the rear bumper will cause the alarm to sound.
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.
