Okay, looks like yet another case of missing info on some RV as I DO find a control listed in the "parts Catalog" here:
https://catalog3d.winnebagoind.com/menu/Parts.htm
Drilling down to the 12 VDC section:
https://catalog3d.winnebagoind.com/2017/311295.htm
We get this shown! Looks like on the forward wall of a basement compartment near the front?
Perhaps check there, but be advised there are two builds of your Rv for that year and I did not check both, so possible that was one of their changes???
Good luck....
