GREEN/BLACK Wire: Immediate, 300mA Duration of Transmit, Channel 3 Output
The Green/Black wire supplies a 300mA switched output whenever Channel 3 of the receiver is accessed.
Pressing both transmitter buttons simultaneously will access Channel 3 and will remain active for as long as the
transmitter button(s) is held. This is a low current output and must be connected to a relay to supply power to the
device you intend to control. Connect Green/Black Trace wire to terminal #86 of a VF45F11 P&B relay or equiva-
lent. Connect terminal #85 of the relay to a fused + 12 volt source. Connect the common, normally open, and
normally closed contacts of the relay to perform the selected function of the Channel 3 output.
ORANGE Wire: Ground When Armed Output
This wire provides a 300mA ground output when the keyless entry is locked to control the optional starter inhibit
relay. Connect the Orange wire to terminal #86 of a standard SPDT relay. Connect terminal #85 of the relay to an
ignition wire in the vehicle that is +12VDC when the ignition key is turned to the on and start positions and off when
the key is in the off position. Locate and cut the low current starter solenoid wire found at the vehicle's ignition
switch harness. This wire will have +12VDC when the ignition key is moved to the start (crank) position and will
have 0 volts in all other key positions. Connect one side of the cut wire to terminal #87a of the relay. Connect the
other side of the cut wire to terminal #30 of the relay.
DOOR LOCK/UNLOCK CONTROL HARNESS
3PIN White Plug w/3 Wires; RED, GREEN, & GREEN/BLACK
The Red and Green Door Lock/Unlock output wires provide either a momentary pulsed ground (-) or a momen-
tary pulsed +12VDC (+) output for controlling a vehicle's power door lock/unlock circuit. To better understand this,
refer to the table below:
Wire Color Function Polarity
Red Lock Ground (-)
Red Unlock Positive (+)
Green Lock Positive (+)
Green Unlock Ground (-)
Green/White 2nd Unlock Pulse Ground (-)
The output of these wires has a maximum switching capability of 300mA. Many vehicles today have factory door
lock relays which can be connected directly to these outputs, however always confirm that the factory relays in
your particular vehicle do not exceed the rated 300mA output of the units door lock/unlock circuit. Plug the three
pin connector of the door lock/unlock harness into the mating connector shell of the control module. Determine
the door lock circuit of the vehicle you are working on and wire according.
WIRING FOR "GROUND PULSE" DOOR LOCK CIRCUITS:
This is a system commonly used on most import vehicle's factory door lock/unlock systems, and with a few
domestic vehicles which employ factory "keyless entry" systems. In this application, the Red wire serves as the
"Lock" output, providing a ground pulse during the locking sequence, and the Green wire serves as the "Unlock"
output, providing a ground pulse during the unlocking sequence. Connect the Red wire to the low current ground
factory door "Lock" signal wire leading from the factory switch to the factory door lock relay. Connect the Green wire to
the low current ground factory door "Unlock" signal wire leading from the factory switch to the factory door unlock relay.
WIRING FOR "POSITIVE PULSE" DOOR LOCK CIRCUITS:
This is a system commonly used on many domestic vehicle's factory door lock/unlock systems, particularly
General Motors and Chrysler, although not on all models. (Please see the note regarding "5-Wire Reverse
Polarity Door Lock Systems"). In this application, the Green wire serves as the "Lock" output, providing a positive
pulse during the locking sequence, and the Red wire serves as the "Unlock" output, providing a positive pulse
during the unlocking sequence.
Connect the Green wire to the low current positive (+12VDC) factory door "Lock" signal wire leading from the
factory switch to the factory door lock relay. Connect the Red wire to the low current positive (+12VDC) factory door
"Unlock" signal wire leading from the factory switch to the factory door unlock relay.
Note: For connection to all other types of factory power door lock systems, including the "4 and 5 Wire Reverse
Polarity" systems found on many Ford and Chrysler vehicles, either the optional Power Door Lock Interface
(Model # AS-9159), or the equivalent 30A automotive relays must be used. Contact the Audiovox
Technical Support Department for additional information on the proper wiring of these circuits.
PLUG-IN CONNECTIONS AND COMPLETING THE INSTALLATION:
Now that all the other components have been installed, and most of the main connections completed, it is time to
finish connecting the remaining plug-in components and completing the installation. Even though these are plug-in
connections, and the plugs have been shaped such that they cannot be plugged in wrong, please read and
follow the instructions for each connection to make certain each component is properly installed.
