That looks like somebody added something. Maybe for some auxiliary lights or something like of the sort. You'll need to trace it to really find out
 
does have trailer brake. i bet thats what it is. thanks guys.

would the brake always have power on the 7pin when brake is applied or would it only come on when the trailer brake control is used?
