Post a photo of your wiper motor as that will confirm if it’s a 2speed or 3 sped motor. A two speed motor is shorter and sticks straight out from the angle portion of the firewall the wiper motor mounts to. A three speed motor is larger and is mounted parallel to the angle portion of the firewall the wiper motor is mounted too. The picture below is of a 3 speed wiper motor.
