terminal 87, to a fused + 12 volt source.  In the rare instance that the vehicle door lock/unlock motor legs rest at + 12 volts
and switches ground to the door lock/unlock motors, connect the remaining terminal 87, to chassis ground.
The Blue/Red wire provides a pulse ground output when the unlock button of the transmitter is pressed a second time
after unlocking the driver's door.  Connect the Blue/Red 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 

green wire

 provides a positive pulse during unlocking, or the 

12 volt unlock

 output.

Connect the green 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 

blue wire

 provides a positive pulse during locking, or the 

12 volt lock

 output. Connect the blue wire to the

wire that provides a low current positive signal from the factory door lock switch to the factory door lock control relay.

3 Wire Positive Switched 2 Step Door Locks

The 

blue wire

 provides a positive pulse during locking, or the 

12 volt lock

 output. Connect the blue wire to the

wire that provides a low current positive signal from the factory door lock switch to the factory door lock control relay.
The 

green wire

 provides a positive pulse during unlocking, or the 

drivers door pulsed positive unlock

 output. Connect

this wire to the 

drivers door unlock

 relay that requires a low current positive signal to unlock only the drivers door. If the

vehicle does not have a separate drivers door relay, one will have to be added.  Locate the drivers door unlock motor wire
and cut it at a convenient location to allow wiring of an optional relay.  Connect the door side of the cut wire to terminal 30
of the optional relay added.  Connect the vehicle side of the cut wire to terminal 87a of the optional relay added.  Connect
the green wire of the 3 pin harness to terminal 86 of the optional relay added.  Connect terminal 85 of the optional relay
added to chassis ground.  Most vehicles door lock/unlock motor legs rest at ground and 12 volts to the door lock/
unlock motor legs for operation, if this is the case in the vehicle you are working on, connect the remaining terminal 87, to
a fused + 12 volt source.  In the rare instance that the vehicle door lock/unlock motor legs rest at + 12 volts and switches
ground to the door lock/unlock motors, connect the remaining terminal 87, to chassis ground.
The Blue/Red wire provides a pulse ground output when the unlock button of the transmitter is pressed a second time
after unlocking the driver's door.  Because the vehicle you are working on requires a positive pulse from the factory door
lock switch to the factory door lock control relay, you will have to add a relay to invert the output polarity of this wire.  Connect
the Blue/Red wire to terminal 86 of the optional added relay.  Connect terminal 85 and 87 to a fuse
 + 12 volt source.  Connect terminal 30 to the low current door unlock wire from the factory door switch to the door unlock
control relay.

Resistive Circuits, As Well As 4 Wire Polarity Reversal and 5 Wire Alternating 12 Volt Door Lock Control Circuits

These applications require the use of additional components which may include relays or fixed resistors. Check with
your technician for information on these circuits or refer to the technical service hot line set up by your product
representative.

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.

DASH MOUNTED LED
2 PIN White Plug w/2 Wires; Red and Blue

The Red and Blue wires in the 2 PIN mini white connector control the anode and cathode of the dash mounted LED.  Route
the twin lead Red and Blue wires from the LED to the control unit and plug the two pin connector into the mating white mini
connector shell of the control module.  Do not force the connector, it will only plug in one way.

VALET/PROGRAM/MANUAL OVERRIDE SWITCH
2 PIN Blue Plug w/2 Wires; Black & and Gray

The Black and Gray wires in the 2 PIN blue connector are the ground supply and Valet/Program input of the unit.  When the
Gray wire is grounded, under certain conditions, the unit will enter the valet mode.  When the Gray wire is sequentially
grounded under other conditions, the unit will enter the various program modes.  Route the Black and Grey wires from the
Valet/Program/Manual Override switch to the control unit and plug the blue 2 PIN connector into the mating blue connector
shell of the control module.  Do not force the connector, it will only plug in one way.  Note:  Please refer to the section;
