My 67 Plymouth came with push to electric wash type switch. The bottle and electric pump are long gone. A scotch lock outside the bulkhead connector connecting 2 wires gets me a intermittent type function. One push gets one sweep and right back to parked. That's temporary switch operation. Same 2 wires attached to a one off toggle switch would cause continuous run and proper park at off. Maybe I would need to hide my properly connected wiper switch behind the dash somewhere. Without knowing what system you have...
