After searching the internet, I found out that I have the American Bosch WWF wiper motor that is upper mounted. First off, are these motors original for a '67? I bought a used windshield frame and I had to drill two extra mounting holes and make 2 holes larger in order to mount the wiper motors. These motors look to me like they were retrofitted by the PO. How do I wire these motors to a switch? The diagram shows what is wired now and the switch that i took from a winnebago. Which of the switch wires connect to the motor wires?
