2 speed wiper motor - only 1 speed
At the motor,
Blue Is full time power with ignition on, trough the circuit breaker built into the switch.
Red is high speed.
Brown/trace Or black is low speed through the resistor.
Green seems to be Connected to the park switch in the motor for final park.
Seems the best I can find to explain it. The manual does not break it down that far. Google for detailed switch info.
