I have a power seat motor that I am using for another application. I have the motor, momentary switch and related moving pieces. The motor contains the two expected power supply leads but also contains a three wire internal sensor that sits adjacent to a magnet on the motor. What I don't know is what that sensor actually is as well as to what and how I would wire it. My guess is that the momentary switch signals a polarity reversing relay to provide forward and reverse power to the motor and that the sensor reads a lack of rotation when the seat has reached it's limit, causing another relay (or another relay within the relay) to cut power. Would somebody be so kind as to help me understand any additional parts I would need and how to properly make this motor and it's sensor work as intended? I am not an engineer but rather one of those people that loves to tinker with things of all sorts. Thank you. I have attached pictures of what I have.
