Euro Headlamp Wiring

[BDBENZ]

After reading dozens of posts, I am still unclear on the wring setup for the 560 SL when converting to euro lights. When I inspected my wiring harness it is a 6 prong plug, not four as referenced in most of the posts. I would also like to hook up city lights and side marker. I believe that this is post 58. Also is it possible to retain the rectangular turns under the bumper?

I could use someone’s past experience.

Thanks,

BD
