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 sensitiv-
ity, 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 # 2 to the off position, then connect the red wire to a + 12 VDC constant 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 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 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.
