Intermittent Wiper Switch Upgrade?

['Cuda_ragtop]

Question for the group.
I have a 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?

Car is a 69 Barracuda.
Needs to have Wash, Slow, Fast plus variable intermittent settings, also needs to "Park" when turned off and between wipes on intermittent settings. TIA

If Iwas going to do this, I would add a addon box under the dash. All it needs to do is intrupt the power from the OEM switch to the slow speed feed on the motor.

I'm sure they are sold. Just need to wire it in. Might even be able to wire it in with matching OEM connectors so no damage to the oe wires.

The parking is already handled by a seperate power source (IIRC)

Amazon 25.00 4 wires
