Don't suppose you have the seat switch available?
Probably wouldn't matter anyway, the seat control probably runs through an onboard computer.

Back in the old days, the power came in central, then the switch position determine the power and the ground for each movement. The direction the power and ground traveled determined which way the seat moved. Power the seats in one direction the seats moved in one direction, reverse the wires, the seat moved in the other direction. Seat movement was: seat front up or down, rear seat movement up or down, and seat track movement, forward and reverse.

Then they added Lombard movement, in or out.

Then heated seats, backrest heat on or off and seat heat on or off.

When they added the computer, everything ran off one or two switches based on a resistance factor for each operation. For the most part, there are no off or no on positions anymore. Good luck!
