BMW wiper motor wiring

[khall]

I am attempting to connect a BMW 2-speed wiper motor to a Lucas three position toggle switch (35927). Both have 5 available electrical pins. I assume that this hookup should allow the motor to park the blades when in the off position like the origional Lucas motor (LW14). I think this is a standard setup used for Backdrafts.
Can anyone help me with the wiring schematic for this combination? I know the numbers for the pins on the Lucas switch and wire colors in the motor harness plug. I need to know how to correctly connect them.

thanks

See if this wiring schematic may help. The wire color connections to the rear of the wiper motor from left to right should be:
- Black - Ground
- Green
- White
- Purple
- Pink
