Dead end wires?

2012 Freelander 23CB

I removed the access panel in the over dinette cabinet to expose the TV plug wiring (antenna cable, 12v plug, house AC plug). There are extra cables there with no indication of what they are or where they go. Must be for options. The white cable on the plug is a ground, but the 3 other cables read nothing. Thoughs?

I want to add a stereo to that cabinet so I need 12v power. It would be convenient if those wires were useful.
