Wiper toggle switch?

[Will84K10]

Has anyone wired an ON-OFF-ON toggle switch to their wiper motor, and if so how'd you wire it up? I will most likely rewire it to the stalk on the steering shaft but there's a ton of wires cut and ripped out from PO and I just need some wipers so I'm not screwed on rainy days.

Well I ended up figuring it out. grounded the center terminal of the switch then ran the purple wire (Hi) to one terminal and the gray wire (Low) to the other. Pretty simple but figured I'd post this in case anyone else needed it.
