Rear fog light wiring
 

For my RHD Boxster i need to move the rear fog light to the LHD side. I did this before on my last UK imported boxster but for the life of me i dont recall what i did.

I suspect to splice the brown wire and move it to the brown wire in the other side connector but that seems not to do the trick, do i also need to do ground..?!

I just look at the photo where i did it and i spot a white is cable? ,, confusing complete perhaps wiring diagram can help me here

Not brown, this link should work:
