6.1 Hemi 69 Barracuda Fastback Father Son Project
That switch looks a lot like this one.

So far no one has confirmed function with a Mopar 69 style 3-speed wiper motor.
Prefer not spending $100 for a maybe, and then not have it work... "¯\_(ツ)_/¯"
I'll keep digging around.
I have some time before needing to put the wiper motor in the car.
Even more before I would need the switch...
Hopefully by then, there will be someone that can say which switch will definitely work.
