That is not that easy as you thought.
The memory switch does not help you at all. It does not work on standard electric seats without more mods.
You would need position sensors, a memory module under front driver seat, new door mirros with 2 motors and a different wire loom for the mirros.
A new wire loom for the seat. To get a rough idea.
Go to my website below and search for the link to Techboy´s page,
there are 13 pages training material for technicians for this system under smm = seat and mirror memory.
