In need of: w203 driver window switch wire diagram descriptions

Hi,

Does anyone have access to, or know what each wire for a 2005 USA w203 C230 is doing from driver door control to switch and vice versa?

MB was nice enough to provide this diagram, that, anyone could plainly have devised from using their eyes if they see in color…

I metered the pins.

Just want to know, definitely, what is supplying power for LED switch illumination and the respective ground for the circuit.

Shoot, even my Haynes manual provided that for the other three doors.

With thanks!
