Does anyone know of a webpage where I can view a wiring diagram for the wiper motor in my 70' Chevelle? I have bought an overhauled unit but I can't figure out how to connect it. It is for concealed wipers. It has 4 connectors, 1 on top of the other 3. My wiper switch has three connectors. I tried to search for previous topics on this but I am still not quite sure what to do after having read through them. Please help! Thanks.
