Gotcha, that's what I figured as only a few high end cars actually have AC ducting to the seats. IMO, that's the only worthwhile way of effectively cooling seats.

Best of luck in your endeavor.

Thanks. Finally got the last connector I needed for the one switch and should have the power circuits wired up this weekend.

I also think I remember reading about a third type of seat out there some manufacturers use or used that uses a piezoelectric device to provide some cooling...?

Did you ever get this completed? I have an 09 sport touring w nav so in my head this process should be plug and play if I pull the trigger on those roadster seats but after skimming through here you got me worried
