6.1 Hemi 69 Barracuda Fastback Father Son Project

Question for the group.
I have a Mopar 3-speed wiper motor and switch.
I would like to add "Intermittent" wiper speeds to by replacing the switch. If you have done this, what switch did you use?
Needs to have Wash, Slow, Fast plus variable intermittent settings, also needs to "Park" when turned off and between wipes on intermittent settings. TIA LIKE.png
