Single or 2 speed wipers on a '64

On Violent, the wiper switch seems to be a two speed. Not sure what options they had. And, honestly, it's been so long since I drove it, I don't remember.

The back of the switch is labeled, B, R, and P (having two terminals.)

The Wiper motor only has two wires, black and LT. Blue.

I need to know what goes where? Is this a two speed wiper system?

All the wiring diagrams I find have a variable speed wiper system, or 9 wires going to the wiper switch.

I've searched on here, and can find nothing that's helpful. I'm not the best at searching though. Can anyone help? A diagram will work, or telling me what color wires go where on the labeled terminals.

Thanks in advance. Kevin.
