I replaced my headlight switch & marked the wires & connections, but some of them fell off, and I am having a hard time putting them back. I have made many diagrams, line traces, voltmeter etc but can't get it right. I need help.

I am including a picture so you can understand.

This may help - it's from teh W123. Online Tech Links Thread - Page 5 - Mercedes-Benz Forum

and this wiring diagram: W201 Wiring Diagram

Once you have the power leads (12 V) correctly identified, you can verify the others by seeing which lights go on when you hit the switch.
