Thanks for the schematic. I'm going to wire mine independent of the switches and turn them on and off via the mirror buttons.
I'm also going to tap into the timer circut from the dome so it comes on and off when you open a door. The mood light will be on with the dash/instruments, I never use the dimmer anyway.

Ok so the C-class base is plug and play? Looked like Rik had corner gaps that had to be filled and his mini visor overlaped his dome controls and wouldn't lay flat.
Your install looked like it had a smaller corner gaps and mini visor layed flat?

Here is an original W124 mount with a W140 auto dim S-class mirror.
