Wires in vent

[Kuettels]

Found white and yellow 14 gauge wires in vent over bed, with no power to them.
Does anyone know what they're for, and where the other end can be found?
Are there wiring diagrams available?

They could be pre-wiring for a second AC unit.

Did you check for DC voltage as well as AC voltage? Check for 12 volts DC.

Only 2 wires, white and yellow = 12 volts. For AC prewire - there would be white black and bare or green, and likely 12 gauge not 14 gauge.

Looks like you are pre-wired for a 12 volt fantastic fan at that vent opening. Likely terminated on your 12 volt fuse panel in a position where there is wire laid down next to a fuse holder with currently no fuse in it, if you see no DC power.
