Confirmation on wiper switch and misc.

I can't read the numbers on the cylinder, boy I wish I could, maybe in my younger days LOL But it's a three speed/variable speed depending on the switch. If you have a three speed switch with three very distinct positions it'll operate as a three speed, if you have a variable speed switch, it will operate as a variable, the switch determines that, but it's a three speed motor

But...
