Good luck with that. It took me three days to find mine and only after I finally got a smart person at Freightliner to guide me through the search.
Those things are never in the same place with two different coaches.
It's probably under the dash, but not necessarily so. It could be in the side kick panel too. Keep looking, if still can't find it, contact Winnabago/Ford to see if it actually was installed. Maybe it wasn't.
