I don't know about "social media" but we have one poster here, who I have secretly named "Debbie Downer" who can always be counted on to find the negative. Many here clearly find what you are attempting to be quite interesting, judging by the thumbs up.
But we have heated discussions here about extension cord adapters, so anything to do with airbags is certain to spark some controversy. Your connector won't win any beauty contests but it looks like it will do the job. I guess you know that if you ever ended up in court after an injury accident that brought the airbags into play that if the other side discovered the DIY project under the seat they would have a field day. But as long as you understand the parameters I say here's to more comfortable driving.
