It appears transferring the old switch and plate looks to be fairly straightforward. Amazingly there's a spot for it on the new seat. Probably a good idea to swap it when the bottom spring is removed. It'll be a bit easier. One phillips head screw for the bracket/switch and two rivets for the plate. Now I just have to get the right sized rivets and it should be good.
Other than using one different color wire for the actual air bag plug, the main floor plug is configured the same as the 2010 main floor plug, with the exception of that extra air bag switch wire used on the 2010.
Pics later if I can get this to work.
