Sounds like a good
mod project!
There should be 2 cone style outlets that uses a 1/4 stereo headphone plug, one at each bunk for
fan-lights.
EDIT: I guess not. I just pulled up photos of 2011's on Google. No fan light outlets at the bunk ends! Very strange. Our '03 Kiwi 17a had them (and was delivered with the fan-lights!), and our 2013 X20E has them (but did not come with the fan-lights). I wonder if the wiring is inside there on yours?
Since I mentioned mods, you might find my
drawer mod of interest. My wife when we were on our last trip how nice it was to have real drawers.
