Could someone explain how to make my windshield nozzles spray on my 67?

I have the foot pedal to spray on my 67 and nothing happens. And I looked closely and couldn't even find where the nozzles are located. Maybe a previous owner did a delete. But if someone could break this down for me so I can have a working spray to clean my windshield while driving I would really appreciate it.

Welcome and that's a nice option.There needs to be hose from the reservoir to the bellows under the pedal,then another to the nozzles under the hood that squirts through the cowl vent at the base of the windshield.
