1965 Valiant washer pushbutton?

Ok my 1965 Valiant wagon did not come with windshield washers. On my 1964 Dart the washer button is a little black button in the center of the wiper switch. I noticed that the wagon wiper switch has a little travel when I push it in and out would that be the button for washer fluid if I had that option? Or did they have a different switch? Please chime in if you have washer fluid option on a 1965 Valiant. Jayson
