I say yes! it adds a nice little flair to the tailgate, I have the ford one wich i believe is the Air Design one and it works perfect with my tonneau cover wich is the hard tri fold one by Ford also and i didn't have to modify anything. If you are doing it for looks then i say YES!
I also have an XL and did the swap using al OE parts and didnt have to do anything extra, i was thinking the same thing about both connections inside the tailgate. It was straight forward and everything worke like it was supposed to when all done
