Hello , I have a 65 Cutlass that i'm trying to get the wipers working again. It looks like someone has modified the wiring. I have a shop manual but it doesnt color code wires and is not that detailed . does anyone have a wiring diagram for two speed wipers . My car has the round motor. Did guys try to convert from single speed to two speed ever. This looks like it could have been a conversion they never got completed. Thanks
