Yes it worked as I can see it. If your RV is Ford based (E450 or F53) thats the unused AUX IN connector. It would connect to the 3.5mm headphone jack on the dash. This jack is only used for the stock ford radio. Since Thor put in a piss poor axxera, this connector is not used and wont cause any issues just danging there or you can also tuck it behind the dash.
