Do you have a multi meter??? Or take a look at the switch the live is always the switched side - earth's are never usually switched for safety reasons.

Found this, really not sure if it helps at all?

Right i've searched through my old paperwork and found my diagrams for when i wired up my Roof screens interior light.

There should be 5 wires going into the light:

Red & White
Black & White
Blue & Yellow
Green with Silver Flecks
Green Orange.

The ultrasonic sensor should then plug in the other side. Take that plug out and unscrew the sensor and fit it somewhere in the roof or screen holder.

The connections should then be as follows:

Red & White - Light on with Door open
Black & White - Light on Permantly
Blue & Yellow - Bulb and last wire on sensor
Green with Silver Flecks - Red wire from sensor
Green Orange - Blue wire from sensor.

which light you on about?

the roof light that turns on with the door?

then there is no earth wire. The "on" selection goes directly to earth.
the red wire goes to the ECU
the blue/yellow wire goes to the live
