Wiper Motor Wires

The wiper switch...............It has two distinct clicks but then rotates quite a bit more after the second click, almost another 90 degrees. There s a 2771378 stamped on the side. I believe this is a variable wiper switch?

That number is the variable 3 speed switch.

Just to add a little more info on the white plate, 2 speed.
It's mine that is the white plate, 2 speed motor. 2822 963
The switch on my car is stamped on the face: 2820525 23199? and 3396 possibly cast in below.
