So, if anyone is still interested, I have a 2014 FJ cruiser and replaced the seats with a set of heated leather seats from a 2013 4Runner. The only issue was that I had to take the position sensor and harness from the FJ driver seat. I had to fabricate my own harness to make the connections to the 4Runner seat. Otherwise, this was a great modification. The 4Runner seats are much more comfortable. If anyone wants details, feel free to ask.
