WIS Brake Switch Electrical Diagram
Replaced the brake switch a few weeks ago to resolve an issue where I couldn't shift out of park. Unfortunately, the problem remains. Does anyone have the WIS electrical diagram for the brake circuit so that I can troubleshoot the other components in the circuit? Vehicle is a 2013 C250. Thanks.

Mercedes c250d brake light
I recently fitted a brabus style defuser and tried tapping in the right rear brake light to power the new one and it's not working, tested with a multimeter and only got 10.3 volts with the car on, I powered the f1 style light directly to 12v car battery and it conformes the light does work.
