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.
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 Wire: ( - ) INSTANT TRIGGER ZONE
This is an instant on ground trigger wire. It must be connected to the previously installed hood and trunk
pin switches.
Brown Wire: - DOOR TRIGGER
If the vehicle's courtesy light switches have a ( - ) 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).
Note for vehicles with interior delay lighting see programming under title "Completing The Installation".
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).
Note for vehicles with interior delay lighting see programming under title "Completing The Installation".
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.
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 30A
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.
