Rear Fog Light 928 S4 1989 US Spec

Hi, has anyone retrofitted or adapted one of the existing rear light positions to add a rear fog light. On the Euro model for example, the fog light is at position C. I hoping there is a simple fix, as I understand that the fog light wiring might already be in the car.

My car is a 928 S4 1989 US spec, which does not have a rear fog light like the ROW or Euro spec models. 

If anyone has done this before with detailed instructions/pictures, that would be great.

GKEJ,
To change to Euro tail-lights, wouldn't you have to actually secure the actual Euro tail-lights?
Or are you thinking there is a way to rewire the fixture for the Euro features?

Hi, I was thinking if it was possible to rewire the existing features, as I believe the fog light connection is in the loom.

Yes, I have on a 1988. It will require soldering. Let me see if I can find my thread on the topic.
