I asked because some models have an easy-access lid on the back side.
Yours does not.
Don't try to pass the wires behind the display.
Not a good idea.
There is room around the sides if you must extend them toward the top. (after a bit of filing)
Better idea, don't extend the wires.
Plan on making them external on the bottom edge of the Kindle.
Mess around with the LED, that hole should be large enough for the wires.
When not in use, wrap around the back and hold down with masking tape.
(With the idea that nobody bothers to watch the colored LED blink.)
