Re: Weird Lights voodoo thing.
There is a plug just the other side of the rubber flexi bit that is under the parcel shelf.
To get the shelf out you need to
1. Take out rear seat base, just yank it from the front edge, a clip on each side, its in tight.
2. Take out seat back, a couple of screws at the bottom IIRC, lift up and release from catches.
3. Thsi allows access to the screws fixing the shelf to the chasssi, undo them.
4. Go into the boot and on the underside you will se a gold coloured nut on a gold colored thread, undo that and its free. Undo the connectors for the stop light the rear speakers if you have them and an earth, and I think that is it, it can be lifted out of the way and the connector is in there somewhere.
It may be available as a separate part, but my disc is playing up at the moment.
