Hoping this will work for uploading a photo of the wiring.
The blue/white pair appears to go through the hole in the center-right of the first picture, and then re-appear, which suggests that it might be feeding the lights (and then continuing to the next light).
The red/white pair seem the heaviest gauge.
There's also a blue/black pair, an orange/black pair, a gray/white pair, and a maroon/white pair. Two of those are presumable feeding the speakers.
There's a 12v + USB outlet panel over the nightstand, 2 over-bed lights, and a 110v outlet all being fed (presumably) by those wires.
Assuming two pairs are used for the speakers, that leaves 3 pairs for over-bed lights, 12v/usb outlet (which could be off the same pairs or separate pairs), and 110v outlets.
Having a wiring diagram to determine which things feed from each fuse and where the wires route, would be particularly useful
If anyone's installed a ceiling fan in the bedroom of a recent Rockwood ultra-lite, then any info/experience would be appreciated. Thanks
