It's a lot more involved than that.

The wiring harness on a seat with powered multiway movement, heating/cooling, etc. will have dozens of 00 gauge wires ganged into a proprietary male plug that can only plug in and communicate to a module that is hardwired to a computer proprietary to the vehicle manufacturer.

I can't even get 2012 mazda rx8 seats into a 2012 mazda speed3 due to the above ^ makes me sad.

Yeah, that’s true especially for modern cars with memory seats. That said, afaik the actual seat controls can still be used with nothing more than a 12v power source. I have not personally tested this on a newer car seat though.
