2000 4.4l Windshield Wiper Wiring Diagram

[Gravy]

G/day Fellas

Appears my rodent attack has created yet another problem, my windscreen wipers will not operate on all speed selections.

Wondering if anyone posses a full wiring diagram with wire colours identified from the switch stalk, thru the relay and thence onto the wiper motor.

At present visual inspection cant locate any severed wires, relay functions OK and the motor operates on both speeds with external power connected.

Appreciate any input prior to departing with the readies and buying a workshop manual.

Thanks in Advance
