someones butchered my factory trailer connection. I have figured out what the taillites and turn signal are and the trailer brake and backup lites but there is a red wire that is hot all the time is it the charging wire if you have a battery on the trailer and there is a black wire that i am assuming is the ground. any help is appreciated i tried the search but no luck thanks again
