Didn't see anything about this but to save anyone a few extra minutes when doing this install (I’m not sure what models this applies to):

I picked up and installed some 07 STI front seats last night. The install was very simple and pain free. The dreaded air bag harness clip that everyone always talks about was a breeze! I bolted up the new STI seats in and plugged the air bag harnesses in. I sat down in the seat for a feel and decided to take the car around the block just to make sure there weren't any vibrations from the seat bolts not being torqued down enough. I tried to put the seat belt in the clip but no go. The 02 seatbelts are too big for the 07 STI seat belt clips! It wasn’t a big deal; just swapped out the clips from my 02 seat and bolted them onto the STI seats and then bolted everything back in (again) and plugged the harnesses back in (again). I love the seats and they are teh sex!!! But learn from my experience and save a little time! That is all!
