Resize memory seats?

Hello, everybody.
==References== I intend to complete the memory seats incl. I want you to remove the wire harness from my car.
However, this depends a little on how much the effort is. Of course, STG, mirror and switch unit should also be out.

Can someone explain where the memory seat/mirror cables are? Or there may be. An overview?
It would be interesting, above all, how the cables come from the driver side to the passenger side.
