I just got an 82 Toyota a month back. It's my first truck. I don't know much about working on cars, but I'm learning. Does anyone know how to wire the washers to the switch. I don't know what B, S, +1, +2, C, E, W means. I attached an image of the wiring diagram. Can somebody explain what these things mean so I can learn how to get my sprayers back online. I need them for the winter season.
