The more I am researching, I believe that part to be the switch component underneath the console which controls it electrically. I can't find a picture of the handle itself anywhere.
Page 101 has the diagram, but I don't see it list the handle. Perhaps it is in another section connected to the transfer case diagram, but I was not able to find it.
Another good catalogue with TONS of switches, but I was unable to find the handle in here either. Maybe these will help someone else though.
In the mean time, I'll keep searching.
