Shock Sensor; Wiring The System; Main Wiring Harness - Prestige APS-25HJ Instruction Manual

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

Main Wiring Harness :

Red Fused Wire : + 12 VDC CONSTANT BATTERY SOURCE
This wire supplies power to the control module and, controls the sensitivity of the voltage sensing
circuit, which detects the turning on of an interior light when a door is opened. This wire will also detect
the switching on of parking or headlamps, and in many cases will trigger the alarm when a thermostati-
cally 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 sensi-
tive 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. The control circuit is shipped with selectable feature #6 turned off, and no change is neces-
sary. If you intend to utilize the voltage sense feature instead of hardwiring, then change selectable
feature # 6 to on as described on page 1 of this manual.
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.
Red/White Wire: + 12 VDC CIRCUIT SUPPLY
See Red Wire above. Connecting the above Red wire completes the connection for the Red/
White wire.
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.
Purple Wire : + DOOR TRIGGER
If the vehicle's door courtesy light switches have a + 12 volt 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 needs 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 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,
and some remote start trigger inputs, will damage the control module.
In these cases 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.
