INST ALLATION OF MAJOR COMPONENTS
Control Module :
Select a mounting location inside the passenger compartment ( up behind the dash ), and secure using
the two screws provided. The control module can also be secured in place using cable ties.
Do not mount the control module in the engine compartment, as it is not waterproof. You should also avoid
mounting the unit directly onto factory installed electronic components. These components may cause RF
interference, which can result in poor transmitter range or intermittent operation.
Siren :
Select a mounting location in the engine compartment that is well protected from access below the
vehicle.Avoid areas near high heat components or moving parts within the engine compartment. Toprevent
water retention, the flared end of the siren must be pointed downward when mounted.
Mount the siren to the selected location using the screws and bracket provided.
Hood or Trunk Pin Switch :
A pin switch is included for use in protecting the hood or trunk ( or hatchback ) of the vehicle. The switch
must always be mounted to a grounded, metal surface of the vehicle. It is important to select a location
where water cannot flow or collect, and to avoid all drip gutters on hood and trunk fender walls. Choose
locations that are protected by rubber gaskets when the hood or trunk lid is closed.
The pin switch can be mounted using the bracket provided, or direct mounted by drillinga¼“diameter
mounting hole. Keep in mind that when properly mounted, the plunger of the pin switch should depress at
least ¼ “ when the hood or trunk lid is closed.
Dash Mounted L.E.D. :
A small red L.E.D. is included that will serve as a visual indicator of the alarm status. It should be installed
in the dash, located where it can be easily seen from outside the vehicle, yet not be distracting to the
driver.
Once a location has been selected, check behind the panel for wire routing access, and to confirm the drill
will not damage any existing components as it passes through the panel.
Drilla¼“diameter hole, and pass the red and blue wires from the L.E.D. through the hole, from the front
of the panel. Firmly press the body of the L.E.D. into the hole until fully seated.
Valet Switch :
Select a mounting location for the switch that is easily accessible to the driver of the vehicle. The switch
does not have to be concealed, however, concealing the switch is always recommended, as this provides
an even higher level of security to the vehicle.
The valet switch can be mounted to the lower side of the dash by drillinga¼“diameter hole in the selected
location.
Be sure to check behind the dash for adequate clearance for the body of the switch, and to confirm that the
drill will not damage any existing components as it passes through the dash. You should also make
certain that the back of the switch is accessible for wiring later in the installation.
Shock Sensor :
Select a solid mounting surface for the shock sensor on the firewall inside the passenger compartment,
and mount the sensor using the two screws provided. The shock sensor can also be secured to any
fixed brace behind the dash using tie straps.
Whichever mounting method is selected, make certain that the sensitivity adjustment is accessible for
use later in the installation.

WIRING THE SYSTEM
Large 14 Pin Edge Connector :
Red Fused Wire : + 12 VDC CONSTANT BATTERY SOURCE
This wire controls the sensitivity of the voltage sensing circuit, which detects the turning on of an interior
light when a door is opened. It will also detect the switching on of parking or headlamps, and in many cases
will trigger the alarm when a thermostatically controlled electronic radiator cooling fan switches on.
When installing this system into vehicles with electronic “ after fans “, it is recommended you disable the
voltage sense circuit.
In voltage sensing applications, the closer to the battery that the red wire is connected, the less sensitive
the voltage sense circuitry will be. Moving this connection point to the fuse panel will increase the sensitivity, and connecting to the courtesy lamp fuse in the vehicle will provide maximum sensitivity of the voltage
sense circuit.
When hardwiring the control module to pin switches at all entry points, the voltage sense circuit must be
disabled. Move dip switch#2totheoffposition, then connect the red wire toa+12VDCconstant battery
source.
White Wire : + 12 VDC PULSED PARKING LIGHT OUTPUT ( 15 AMP MAX )
This wire is provided to flash the vehicle’s parking lights. Connect the white wire to the positive side of one
of the vehicle’s parking lights.
White w/ Black Trace Wire : POSITIVE OUTPUT TO SIREN
Route this wire through a rubber grommet in the firewall, and to the siren location.
Connect the white / black wire to the positive wire of the siren. Secure the black ground wire of the siren to
chassis ground.
Black w/White Trace Wire: LOW CURRENT NEGATIVE HORN OUTPUT (300mA MAX CURRENT)
The Black w/White trace wire provides a 300mA pulsed output to beep the vehicle's horn. This low current
pulsed output should only be connected to the low current switched ground output from the vehicle's horn
switch.
If the vehicle switches high current ground or + 12 volts to the horn, a relay must be used to operate the
vehicle horn. Connect the Black w/White trace wire to terminal #86 of a VF45F11 P&B or equivalent 30 A
automotive relay. Connect terminal #85 to a fused + 12 volt source. Connect the remaining relay contacts,
87, 87a, and 30 to perform the switching function the vehicle's horn circuit requires.
Purple Wire : + DOOR TRIGGER
If the vehicle’s door courtesy light switches havea+12volt output when the door is opened ( most Fords
and some Imports ), you must connect this wire to the positive output from one of the door switches. In
most cases, the purple wire will only need to be connected to one door switch, no matter how many doors
the vehicle has.
WARNING : Do not use the purple wire if the vehicle has ground output type door switches.
( see Brown Wire ).
Yellow Wire : + 12 VDC IGNITION SOURCE
Connect this wire to a source that is live when the key is in the on and crank positions. Be sure that this
source is off when the key is in the off position.
Dark Green w/ White Trace Wire : ENTRY ILLUMINATION ( 300 mA MAX. )
The dark green w/ white trace wire provides a 20 second ground signal whenever the system is disarmed,
and pulses ground whenever the system is triggered.
It should be used to provide the ( optional ) entry lighting, and to flash the vehicle’s dome light while the
alarm is sounding. This is a transistorized, low current output, and should only be used to drive an external
relay coil.
Page 3
Connect the dark green with white trace wire to terminal 86 of the AS - 9256 relay ( or equivalent 30 A
automotive relay ), and wire the remaining relay contacts according to the polarity of the dome light circuit
in the vehicle.
NOTE : When wiring this feature in vehicles with factory equipped delay lighting circuits, it is
best to connect to the output of the timer which feeds the dome light, rather than at the
door switch. This will ensure that the dome light pulses when the alarm is triggered.
Dark Blue Wire : DELAYED 300 mA PULSED OUTPUT / CHANNEL 2
The dark blue wire pulses to ground via an independent RF channel from the keychain transmitter. This is
a transistorized, low current output, and should only be used to drive an external relay coil.
WARNING: Connecting the dark blue wire to the high current switched output of trunk release circuits,
some remote start trigger inputs, will damage the control module.
Connect the dark blue wire to terminal 86 of the AS - 9256 relay (or equivalent 30 A automotive relay), and
wire the remaining relay contacts to perform the selected function of channel 2.
Black Wire : CHASSIS GROUND
Connect this wire to a solid, metal part of the vehicle’s chassis. Do not confuse this wire with the thin black
antenna wire that exits the control module independently.
Orange Wire : 300 mA GROUND OUTPUT WHEN ARMED - N. C. STARTER DISABLE
This wire is provided to control the starter cut relay. Connect the orange wire to terminal 86 of the relay.
Connect relay terminal 85 to an ignition wire in the vehicle that is live when the key is in the on and crank
positions, and off when the key is in the off position. ( This is where the yellow wire from the alarm should
be connected ).
Cut the low current starter solenoid wire in the vehicle, and connect one side of the cut wire to relay
terminal 87A. Connect the other side of the cut wire to relay terminal 30.
Note : This is a normally closed starter cut arrangement, and when power is removed from the
security system, the starter disable feature will not operate, allowing the vehicle to start. Audiovox
does not recommend using the Orange wire to interrupt anything but the starting circuit of the
vehicle.
Brown Wire : - DOOR TRIGGER
If the vehicle’s courtesy light switches havea(-)ground output when the door is opened ( GM and most
Imports ), you must connect this wire to the negative output from one of the door switches.
WARNING : Do not use the brown wire if the vehicle has + 12 volt output type door switches.
( see Purple Wire ).
Light Green Wire : ( - ) INSTANT TRIGGER ZONE 1
This is an instant on ground trigger wire. This wire ( zone ) should be reserved for connection to optional
ground output trigger devices such as motion and / or shock impact sensors.
Dark Green Wire : ( - ) INSTANT TRIGGER ZONE 2
This is an instant on ground trigger wire. It must be connected to the previously installed hood and trunk pin
switches.
2 Pin Blue Connector : VALET SWITCH
Route the grey and black wires in the 2 pin connector from the valet switch to the control module, and plug
it into the mating blue connector on the side of the module.
2 Pin White Connector : DASH MOUNTED L.E.D.
Route the red and blue wires in the 2 pin white connector from the L.E.D. to the control module, and plug
it into the mating white connector on the side of the module.
4 Pin White Connector : SHOCK SENSOR
Route the red, black, blue, and green wires in the 4 pin white connector from the shock sensor to the
control module, and plug one end into the shock sensor, and the other end into the mating white connector
on the side of the module.
Page 4
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.
4 Wire Polarity Reversal and
5 Wire Alternating 12 Volt
Door Lock Control Circuits
In these applications, the AS 9159 Door Lock Interface ( or equivalent 30 A automotive relays ) must be
used. Refer to the AUDIOVOX Door Lock Wiring Supplement for proper connection 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 : 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.
