I have fitted electric seats in my car, the wiring for the heaters was already there but not the movement.
Also in Saab's wisdom they had changed where the wires were placed in the plug.
Also another odd thing my car (2002) had a sensor on the passenger seat that told the Airbag module if the the seat was to far forward, the later seats did not have this but as my car was looking for it I had the swap the sensor across from my old seat. The hole was there for it but the threads had never been used, probably cost cutting?
If you want memory that is more complicated so I just fitted a switch from a non memory seat and got the appropriate trim. It sounds more complicated than it actually was but it all works and no warning lights.
