David,
I believe the driving/fog lights are bigger than the turn signal fixtures and mount differently as well. See attached Euro car pictures. A white US car is attached which shows the turn signal mounting position. They do seem to be different.
Do you have any mounting provisions between the grille and the headlight tower? Does the wire length suggest it could be for the driving/fog lights? Unless your front fenders were replaced, seems like you should have a hole or two for these. Maybe if the car has been painted, the holes were covered up? I just noticed that your bumpers have the rubber strip. I believe this is just for the low grille cars.
I hope this helps,
Wallace
