Welcome to the site from snowy Minnesota! Congrats on the new camper I'm sure you are anxious to use it as you wait for the white stuff to go bye bye we went thru the same feeling a year ago as we bought ours in December as for the red switch if its like ours it is a disconnect and ours turns and pulls out so you will know its disconnected, at any rate welcome again and feel free to ask any questions here everyone is very helpful and nice, I know I have learned many things just from reading posts, so have fun with the new camper it won't be long now... Hopefully
