Hello, my Porsche 924 Turbo B.J. March 1980 which I bought in USA is finally there. It has to be upgraded now to ( H ) license plate TÜV. The Sealed -Beam headlights must be converted to H4. Do the headlights I get here without remodeling? or does something have to be converted? A typical crack point is the light switching with sidemarker and flashing sidemarkers. To upgrade I need both schematics, the US and German. Who can help me with this? s do I still have some modifications or changes?? Who has had to deal with similar problems? Greetings theo
