Dodge AT4 Wiper wiring

Hi All,

I removed my dead wiper motor. Popped down to the wrecking yard and grabbed the original looking wiper motor and wiper switch from a Dodge ambo there.

Motor has;
white, red, green

Switch has;
white, red

Anybody know how to wire this?
Can anyone tell me function? single speed? two speed? other????

Not 100% without personally testing it but id say it should earth on the main housing of the unit and green would possibly be common or power and red and white would be the functions cant be 100% percent, sorry for being unclear just a bit hard when unsure of what the unit looks like feel free to pm me mate

I hope this helps
