The fill plug, drain plug are both on the back side of the transfer case facing the rear drive shaft. They are the two biggest nuts on that side of the transfer case. I have yet to determine what size the plug actually is I'm guessing either a 1 3/16 or a 1 5/32, since a 29mm or a 30mm will not fit it.
