[TR] 2-speed wiper wiring diagram

[carlsereda]

Hi Ed,
If you have any luck finding specs can you keep me in the loop? 
I believe the way 2-speed wiper motor works is when you turn on the second
click of the 2 -position switch, a secondary winding on the field coil (simply
about 50 rounds of extra wiring over the standard field coil) is activated,
giving faster armature action. Otherwise I think all else is same as a
standard 1-speed unit.
Regards,
Carl
