Wire routing near Bathroom? 2016 13' Scamp

[Catya]

Hello,
I'm trying to find out where the wires around the bathroom are located.
I need to run a wire from the charger to the battery (temperature sensor).
If they aren't obviously accessible, have any of you successfully fished wires routed past the bathroom?
Thank you,
Catya

The wires come into the trailer near the closet floor. Then they go between the bath liner and shell to the bottom of the kitchen cabinet. Try a wire snake. Or drill a hole in the floor on the outside the frame rail and attach the wire to the frame rail with straps or use clamps and short screws and attach your wires to the bottom of the floor. The second would be the easiest way to get to the battery box.

Thank you, Eddie.
Just be be clear, they go around the outer perimeter of the bathroom towards the front, not under, along the door, right?

yes.
