Jerry...Please, and thank you.
The motor has three terminals, a single (power) and a pair at right angles. I can't tell how many this one in the photos has b/c it looks like that may be a terminal in the center.
Check out this YouTube video. It's the same as my motor, but the shots of the switch are hard to make out.
'58-'59 elec. wiper If you've got a two-speed switch (that's what my motor is) and are willing to part with it let me know!!
