I swapped both My Driver and Passenger Powered Seats for Recaros.
The Driver worked fine but the Passenger Did not work at all.
I would assume it would be the Same for GT500
Did you do this yet?
Well good news! I just did this.... Everything swapped over easy as could be! Just unbolt the seat, swap, re-install and you're done! Power seat worked on the car that had the recaros, no fuse addition, no wiring, etc. And the recaros worked perfectly in the car that had the normal power seats. Better yet, NO AIRBAG LIGHTS!
Easiest swap ever!
