Fixing up a beaten '82 c30 cab and chassis. The wiper switch literally fell apart when I pulled it out. Replaced it and still no luck. The wiper motor had some hack universal pump butchered into place, so I replaced it. Still no luck. 12v on three wires at the wiper, so I'm guessing the switch grounds it. Tried to download the PDF, but I'm having issues (firewall). Which wire at the switch provides the ground?
