Variable Wiper Alternative

There are several differences so what works for mine may not work for all. My wiper switch has a push to wash function. That sends power to the washer pump and nothing more. The later model switches would rotate to low speed when pushed and they will reverse the wiper direction to park. Mine did neither of those.
I switched to a foot operted washer pump setup. I attached the brown wire that did go to the electric pump to the motors park switch. Now one push of the switch knob produces 1 wiper sweep/cycle and back to the park position. No it isn't a variable intermittent but no fancy electronics were needed either.
