Triumph Repair: TR7 wiper motor wiring, orange and green, wiper motor

Question
Hey Jim I have a strange question. I am working on a friends car that has a TR7 wiper motor installed in it and he would like me to wire it to his switch. I have been all over trying to locate a wiring diagram with no success.
Here's the question. The plug from the motor has 5 wires red/green,blue, black, green/orange and green/brown. Can you tell me what each are for?  Thank John

Answer
John,

Got me confused.  There should be a wiring harness with connector on it for the wiper motor.  Or is this wiper motor in a non-Triumph?

According to the factory, there are 5 wires at the wiper motor end.  They are:

Blue/Light Green  :  High speed brush
Red/Light Green   :  Normal speed brush
Brown/Light Green :  Limit switch connection
Black             :  ground
Green             : +12V for automatic park

Cheers,

Jim
