NHTSA Complaint #11559019 — 2007 SUZUKI XL7

I have this airbag light on problem stated below. It seems it should be a safety recall. Possible solution for Airbag light on Seat Sensor Ok, I'm going to ask a couple of questions and hope that [XXX] or someone with knowledge chimes in. I originally had this problem in my wife's car a couple of months ago, airbag light on, clock flashing after going over a bump with my 240lb ass in the passenger seat. We got home, turned the car off, restarted it and it went through the power-up self test I guess and the fault cleared itself. The other day it started up again, no bump but still had the fat guy in the seat. I noticed that I only saw this issue referring to 2004 model xl7s. I've looked and haven't seen 2003s, or 2005s. The TSB for this issue ONLY refers to 2004 models and says that this is the updated part number 86605-53JA1. If you look at this site that has them in stock: [XXX] It says that part fits 2004-2006. I found the published date for the TSB somewhere online as 12/2004 so they apparently knew the problem early, made an update/change and moved on. Probably changing the design sometime mid-year 04? I don't like the idea of spending $1400 for a part. So, I checked [XXX] and found a nice passenger seat from a 2005 locally for about $75 in a boneyard. Does anyone have any advice why swapping in a 2005 seat (or just the base if the color is wrong, whatever) is a bad idea? Does anyone know if there has to be any special dealer magic/ calibration/ etc done if I put this in myself? I haven't yet had the time to pull the seat out of the car, flip it over and check things out. But I'm not super hopeful that I can fix whatever this sensor is since nobody else has posted anything in the last 13 years. Thanks for your interest.
