Well with no responses I went at it blind.. was not as simple as hoped but successful non-the-less:
The whole back liftgate single trim panel needs to be removed.
Remove four (4) phillips screws and one Torx 15 screw (at bottom - tricky to angle at).
Using a trim stick or another suitable wide flat-bladed tool, carefully pry the trim panel away from the inside of the liftgate to release the push-pin plastic fasteners that secure the panel to the liftgate.
Disconnect the lamp from the lower liftgate trim panel. The clear plastic lamp cover popped off on its own (which released the lamp from the panel) when i popped off the trim panel - so dont step on it. When re-installing: you should release the wire connector (squeeze and pull) from the lamp and align and snap together the clear plastic cover and the now separated lamp into the lamp hole in the panel. Then when holding panel back into place you can simply plug the wire connector back into the already installed lamp)
Remove the liftgate lower trim panel from the vehicle.
Remove the liftgate watershield.(black insulating foamy piece that covers up the latch area at the base of the door).
There will be two wires , one black and the other Violet with orange stripe running to a connector on the latch. I could not see very well or access the connector inside the door panel so I actually had to completely remove the latch by unscrewing the three (3) torx 30 screws in the underside/base of the door. Once the latch is free you can pull it out in order to access the connector. Squeeze to remove the wire connector.
Once disconnected you will no longer get the Liftgate is Open warning light and the interior lights will no longer be foreced on while driving. Although the intereior lights will no longer automatically come on when accessing the liftgate. This is not a big deal to me because when you unlock the car using your keys, the interior lights come on anyway (which i always do when accessing the liftgate).
There is a service bulletin (see first post above) that outlines switching these wires to resolve the erroneous Liftgate Open warning that may allow you to reconnect and have the liftgate return to normal operation. However, I am not terribly gifted with electrical and saw no easy method to dismantle the existing connector in order to easily switch the wires. Only method i could see was to cut and strip the wires above the connector and reconnect/switch wires that way (by soldering and using shrink tubing - or just twisting and using electrical tape). Anyway.. i was doing this all in 10 degree weather in chicago in my driveway and was not looking to be out there any longer (had lost feeling in my hands/toes) so just disconnected and am happy to no longer have the Liftgate ajar warnings!
