Rallye dash and wiper switch question

all 3 speeds switches have the push to wash feature & therefore must use the electric washer pump located in the fluid bottle. Manual washer pump (on the floor board, use only the 2 speed switch & wiper motor.)

Not exactly. Push to wash feature in my 67 is jumpered to the wiper park circuit ( simply a scotch lock connector at bulkhead ). One push equals one sweep intermittent operation. Foot pump washer added. This doesn't work for those late model switches that self rotate to low speed when pushed.
