48BT is right.. there should be little metal pipes in the vents on the cowl. The wiper switch has a push button on it that turns on the wipers at the same time. The pump is attached to the wiper motor, but it's easier to put in a generic electric washer pump than try and get the mechanical one going. I'd have to double check my truck, but I think the rubber line comes into the cab and then up. Washer bottle mounts on the left of the radiator, just above the regulator. Atleast it does on my 63.
Hope this helps.
