Passenger rear mirror switch question
My '89 560SEC uses switch 124 820 18 10 to control the passenger side rear mirror. I am hoping to see if the switch is malfunctioning. The six connectors are numbered but I can't determine which is the power connector. I'm thinking it's either #4 or #3. Does anyone know?
