Does anyone have a wiring diagram for a 2 speed wiper motor? Can’t figure it out. My motor only has 2 terminals on it that I can see. One is 12V ign when you ground the other terminal I get one speed. Not sure how to get the second speed as I don’t see another terminal. There is 2 terminals on the squirter motor. Tried grounding those and get nothing. Any help would be appreciated.
