Hy Old Blue 1978, as far as I am aware there were no factory installed windshield washers. I think what you have found is part of an aftermarket kit, the pump was a rubber diaphragm that was mounted on the floor usually by the dimmer switch and it was operated by pumping with your foot. Nozzles and tubing to plumb them came with the kit along with instructions on where and how to install them, hope that helps.
