Wiring question.

I purchased a 2003 Coachman 25' trailer that had a bedroom that was partially gutted. There is a junction box under the bed. Two of the trailer light wires were disconnected from this box. Does anyone know which wires the trailer light wires (green and white at top of pic) connect to in the box? I will try to add a photo to this post.

Well the whites are obviously grounds. Everything else is kind of a guess. But standard wiring would be
Blue - Electric brakes.
Brown - Tail and running lights.
Green - Right turn and brake.
Yellow - Left turn and brake.
The two thick red wires are battery charge.
The black wire in with the red charge wires is possibly the emergency breakaway switch power.
Not sure on the little reds, they could be the breakaway wires instead of the black one..
Not sure on the single capped off yellow green or white wires.

Do all the lights work?
