Hi !!
Just to inform you all that my foglights are now working perfect, and is wired via the main light switch. fog position.
Next to the fusebox (in my car LHD; on the left side, there are 3 wires coming out of the main wiring loom. 2 blue/yellow 1,5mm2 and one red/yellow 2,5 mm2.
All these three are to be wired together to get the lamps to work when opering the main lamp switch to fog position.
No connections needed to be done in the fuse box.
Both blue/yellow wires will be easily spotted in the engine compartment, left and right side, next to the headlamps. Earth is also easily spotted here.
The fog lamps are working together with the parking lights, which at least in Norway, is the only way they are permitted to work, i.e. not in connection with the main beam. As soon as the main switch is switched to main beam, the fog lamps come off.
Hope this will be of help tto anyone else fitting fog lights to their P6's.
Anyway, thanks a lot for all your help.
Regards
Petter
