I don't know, but the seats are the same. the heated seats just have heating pads stuck under the seat cover and a wire to the loom underneath.
There are two electric seat systems, just the driver's seat with the elecric adjuster switches, and the memory driver's seat with the eelcetric passenger seat (non-memory).
I think that the driver's seat just needs an electric feed, but if you fit the memory electric seat, you need them adding with Tech2 as far as I can see, the I-Bus signal is needed to move the mirrors and recognise the other stuff.
