This is an option on my 70SS, but all the hoses from the resovior to the windshield have been disconnected.

It appears that there is tubing from the resovoir to the firewall, thru a gizmo that is 3-4 inches long and then to the washer pump. But, all of the hoses have been disconnected, so I don't know what is an inlet and what is an outlet.

AND, how is the washer fluid level monitored.

Thanks
