Wiring Loom for control panel - where does it run?

[sewb]

Hi - does anyone know where the wiring loom is which runs from the rear battery to the control panel. VW have looked behind the cupboards and apparently it is not there. They 'think' it might be under the floor and are preparing to lift the floor - but I would rather know for sure where the wires run before they do this. Thank you

Assuming a late 6.1 it's a single purple yellow wire? See diagram 75/3. Camping equipment in the resources section.
