Concentrate on this m8s ...here is the essence of it :

When a door is opened the BCU provides earth paths from the interior lamps,
the load space lamp and the ignition switch illumination through the BCU. The
earth path(s) from the lamp(s) is on PU wires, through header C0723 and
C0285 LHD/C0294 RHD to the BCU pin C0663-9.

U'll find these in RAVE Connector views...
also u can run circuit tests with nanocom/hawkeye for these... otherwise is a quite big job with a multimeter to locate where the earth is lost.
