Its 2002 Manual bog standard club with no bells or whistles. Not sure what photos would achieve to make this post more worthy.

I shorted the switch connector and nothing. K109 behind the glovebox is the feed to all things connected with the reverse switch. Pin 19 is the one fed from reverse switch, and when its in reverse gear, ignition on I get 12V. Move it out of gear and it returns to 0V. This rules the switch out.

Testing continuity again shows pin 15 LH reverse light circuit is open but RH see's 12V. But I did get 12V on LH when first checking. It appears that the problem lies between glovebox K109 and rear connections. Is there another connector buried in the car under seats?

On the RH rear connection, there's 12V but as soon as the bulb is fitted it goes to 0V. Can't be an earth issue as the rear lamp bulb holder is common earth and the other lamps all function.
