A friend disconnected my wiper motor wiring without labeling it. I am about to hook up a new motor. How does it hook up? Four terminals on the switch and three on the wiring.
Assuming the wire presently connected to the switch is circuit 71-18 (key switched power), then you should be dealing with the lower three terminals grouped together in an upside down pyramid for the motor interface. The bottom center terminal should be (A)-Black, the left should be (P)-Green, leaving the right as (F)-Red.
