I don't know if a wiring diagram exists or if plans exist for any of the trailers, I would think that the dealer could tell you though. If any of this does exist then it's a closely guarded secret because I haven't seen this information anywhere or been able to get copies of this. I guess you just want to know where things are behind the walls before you start drilling holes and I don't blame you. Sorry, I know that this doesn't help much.
