I have two "broken" units apart. On both,
Black is ground and goes to one side of the motor directly.
Red goes to the pole with the mechanical switch then to the other side of the motor through diode / thermistor
Yellow I can't see it is connected to anything (should be directly connect to motor though diode / thermistor
I thought that when the wiper is to start / run, both Red and Yellow are energized. When the wiper is to stop, the yellow is disconnected and the wiper will run until the mechanical switch is opened when wiper is in rest position and the motor is cut off.
Can't seem to see where yellow goes....
