Glad you got it and worked thru it.
Log trucks I've worked on do not supply the 2 different connection boxes ( combined and separate brake lights) that would be nice if they did. Most motorcycles don't have enough power to run trailer lights, then you need to get into a separately powered trailer connection, but I digress.
Glad you got it figured.
