Bosko - did a search, just didn't search for "POS seat problems". Good thread though, thanks.
I did the re-wire..for the record I don't thinks it's two power and two grounds. It was like cjones referenced; there are 2 power (green) and one common ground (12 gag black). The third wire is grayish-brown with a blue strip and is for the seatbelt chime. Since the seatbelt connector is removed for our cars anyway, I just left this one alone.
Methodical - as far as where to get seats, you really just have to keep your eyes on the classifieds and see if any are in your area. Check if there are any local clubs or club web sites too, these are great resources.
