2556 Command Bridge Cabin Light issue-gctid816643

[Guest]

Does anyone know where the + - wires for the V berth cabin lights on a 2556 Command Bridge originate. No power to both V berth light boxes. The main cabin lights have an access panel in the ceiling. I have these all working including the light in the head. The V berth is sealed. I can feel the wires under the felt headliner. They end in the corners however I do not see where the originate on either side. I looked in the ceiling panels and all wires either go to the bridge or to the main cabin ceiling for lights and speakers horn etc. Where do the white and black wires for the overhead lights in the V berth come from? Behind the AC panel near the radio? I'm ready to look there next. Thanks
