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.
