Have you tried this? Because I remember reading somewhere that you need to reverse engineer the protocol they use to send the seat commands and that's a bit harder than simply hooking it up to power. I could be misremembering, I haven't tried it myself.
A lot of times the controls are on the seat itself, so for adjustments you’ll just need 12v power. For heating/cooling, I suspect it’s more complicated. On older cars, it might just be a wire you need to jump for hearing.
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.
