There are five wires, two large and three small. The two large green and red) go directly into the motor. The three small stop at a connector attached to the motor, then go in. I can feed juice at the pigtail connector.
The big wires are the motor, the three small wires are the feedback potentiometer to the seat memory system. Just feed +12V to the motor to test it, and reverse polarity to go the other way.
