Rear Slide Control Board died

For those of you who have a 2004 or2005 Itasca Sunova or Winnebago Sightseer; a question. Where is the socket for manually cranking in the rear slide? I have looked everywhere and cannot find it. I suspect it is under the trim piece on the bottom of the slide, but I don't want to take that off unless I am sure that is where it is. I have looked in the two bins on the right side and the bins on the left side. The tube that contains the worm gear shaft is clearly visible on the bottom of the slide but no way to access it? By the way it's not in any of the manuals. They only talk about how to manually crank the front slide and the sockets are right there when you open the bins on the front slide. Still looking for a control board.
