Thank you so much for that link, it will help so much. You just saved me a couple of hours. but I am still confused on this 4 pin and 6 pin connectors. In the picture of the new euro headlights it uses 4 pin connectors, I think. I am a newbie at this but, I will have my uncle help, he is a mechanic and a very good one at MB. I am just puzzeled at how the old connector goes into the new one, or if the old one needs to be modified.

I havent bought the headlights just yet, I wanted to make sure it was possible before I spend $250.
