    What are the wire colors on the potentiometer and on both sides of the connector??? I can probably figure it out with correct color coding.--Kent

    I need to pull the seats again to get the exact colors. I think the wire with the black stripe on the potentiometer is the wiper. I just need to figure out which of the three wires on the car side connects to the wiper. I'm going to use trial and error next time I pull the seats. When the seats work in both directions with the potentiometer connected, then I have the correct connection. There are only a few possibilities, so it shouldn't take too long.

    I have resolved the wiring issue. I had to purchase a new potentiometer for the driver's seat, so I bought a factory part. I used it as a model to determine the wiring for the non-OEM potentiometer on the passenger seat. For the non-OEM potentiometer, the white wire goes to the brown wire on the connector, which is the wire furthest from the connector lock. The yellow/white wire goes to the yellow wire on the connector which is the wire in the center. The black/white wire goes to the pink wire on the connector which is the wire closest to the connector lock. See the pictures. My top is now working.

    If you are going to repair your potentiometers, please read this first:
    After you put the new potentiometer on the seat, DO NOT screw the seat back in place. Use the seat controls to move the seat all the way one direction, then connect the potentiometer. Next move the seat all the way in the other direction, then all the way back. You will notice that the seat will not move all the way to both extremes. It needs calibrated with an SD1 computer at a shop. When you screw the seats back in, make sure that the connectors for the potentiometers are in front of the power seat motor where you can reach them after the seats are in. Since the seats do not move all the way, you may need to disconnect the potentiometer at some point. This will allow you to move the seat to both extremes so that you can remove or install the seat screws. The potentiometer tells the computer when to stop moving the seats. With the potentiometer disconnected, the seats will move all the way to both extremes.
