As Owen said, The co-ordinator works in conjunction with the bottle and is vacuum operated. When the spray cycle starts, that gets a vacuum to move a piston inside. It starts the wipers independent of regular wiper switch. There is an air bleed screw and when water stops & vacuum disappears, the screw slowly admits air and a spring forces piston back and stops wipers after a few seconds. Whole washer system was an option, but that would be part of it so maybe it was donated to another car long ago.
