I am very sorry my German is not very good, but I am sure most of you guys will understand english
 I managed to get these up and running, I didn't find any help online so I decided to tackle this with a mate : 
I bought the smoked lights from FK automotive in Germany but the lights are made by DEPO Taiwan 
The aftermarket lights have a foglamp on each side so they will work irrespective if the car is left or right hand drive. 
we had to use a soldering iron and solder cables to the pins of the aftermarket lights and we did cut through the factory plug and crimped universal  aftermarket plug  6 pin which
you can buy from most auto shops,
