77 as I recall, which has four wires at the wiper switch. Green to
red/light-green for slow, green to blue/light-green for fast. A simple
on/off switch would disable the park function, but if you get a change-over
switch connect the red/light green to the common, the green to the 'on'
position, and brown/light-green to the 'off' position. That would mean you
would be restricted to slow speed, using the high-speed winding for parking
may not be a good idea.
