Once everything is loose and pulled forward You will finally see the holy grail the final screw. All that to get to this one screw! Undo it and you can now remove the bottom dash. From here I would do all you wiring and switch assembly under the dash then put everything back together and plug in the upfitter switches and follow the rest of the guide to hook it up to the battery. Hopefully this helps someone. I looked everywhere and so nothing of how to actually remove the bottom of the dash completely.
