Hi,

Does someone know what is the wiring for the rear window defroster out of a 1991 300D? I want to use this for manual on/off of aux. Radiator fans.


I am guessing that power to led on switch is handled by 2 and the rest is power in/out lines and ground. I have:

1 Solid Black
2 Black/Yellow
3 solid brown
4 blue/gray
5 solid blue.



front of switch



Thanks!
