Wiper wiring help needed

[Wynand]

I run into problems trying to sort out the wiper wiring and desperately need help.

I have a new wiper motor for a Toyota Hilux truck and new wiper/lighting stalk for a Toyota Corolla (late 90's early 2000 model). I tinkered with the wiper motor and found low and high speed wires, altough it goes faster on both speeds when reversing the wires :?: I can probably sort the wiring out to have a two speed affair but the motor would not park in its designated stop area.
How do I wire it correctly from the stalk to the wiper motor ignoring the relays for the moment so it will have both low and high speed and will park correctly?

Control stalk wiring are the following dicounting the two thinner washer wires;

1. Blue with green stripe
2. Blue with white stripe
3. Blue with red stripe
4. Blue with black stripe

The wiper motor has the following wires;

1. Blue with white stripe
2. Blue with red stripe
3. Blue
4. Yellow
5. Black (I assume this will be an earth/negative wire)

Can anyone help? Thanks.
