Unused Dash Wiring

[SubUrban Legend]

To the right of the speedo cluster in my 1999 Surburban, there is a set of three plugs that were to be used for option switches for options not on this vehicle. There are three plugs with color marked wiring harnesses. IIRC, there is a white taped harness, a yellow taped harnes, and a green taped harness. Any clue what they are for? I know that it is not hatch release or rear wiper as it has cargo (barn) doors on the back and probably not for the non manual 4WD switches as it has a lever.

When I swapped out my dash, I saw them as well. I have not as of yet checked my shop manuals, but I would be willing to bet they are for the "Autotrack" 4WD. I also have the manual floor mounted selector.
