w 202 94 c220 need wiper switch pin plug number wiring
 

have a 94 w202 c220, recently lost the high speed on the wiper, i can use intermittent and low speed.
i am thinking of finding the pin wire on the plug and run my own power to it so i get high speed.
my friend is in the same boat with his c280, he losted the int , low & high speed on the wiper.

my under cover is off so is easy to find the wires.

there si a big plug from the steering stalk switch on the w126.
i dont think this car is any different.
thanks in advance
