WHITE/BLUE Wire: Immediate, 300mA Duration of Transmit, Channel 4 Output This wire supplies a 300mA switched
output whenever Channel 4 of the receiver is accessed. Pressing A combination of the transmitter Lock/Unlock buttons
simultaneously will access Channel 4 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 this wire to
terminal #86 of a VF45F11 P&B relay or equivalent. 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 4
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; GREEN, BLUE, & BLUE/RED
The Green and Blue Door Lock/Unlock output wires provide either a momentary pulsed ground (-) or a momentary pulsed
+12VDC (+) output for controlling a vehicle's power door lock/unlock circuit. To better understand this, refer to the table
below:
The Blue/Red trace wire will provide a pulsed ground only and will only provide an output when the lock/unlock button of
the transmitter is pressed a second time after a first unlock command was issued. This is used for second step unlock
or all doors unlock in a two step circuit. In this arrangement, Green is used to control the drivers door unlock relay and the
Blue/Red will be used to control unlock of all other doors.
3 Wire Ground Switched Signal Step Door Locks
In this application, the green wire provides a ground pulse during arming, or the pulsed ground lock output. Connect the
green wire to the wire that provides a low current ground signal from the factory door lock switch to the factory door lock control
relay.
The blue wire provides a ground pulse during disarming, or the pulsed ground unlock output. Connect the blue wire to the
wire that provides a low current ground signal from the factory door unlock switch to the factory door lock control relay.
Blue/Red wire is Not Used.
3 Wire Ground Switched 2 Step Door Locks
In this application, the green wire provides a ground pulse during locking, or the pulsed ground lock output. Connect the
green wire to the wire that provides a low current ground signal from the factory door lock switch to the factory door lock control
relay.
The blue wire provides the first ground pulse during unlocking, or the drivers door pulsed ground unlock output. Connect
this wire to the drivers door unlock relay that requires a low current ground 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 blue wire of the 3 pin harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay
added to a fused constant + 12 volt source. Most vehicles door lock/unlock motor legs rest at ground and switch +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
