In 2015 you could buy seats with or without airbags. My 2015 does not have seat airbags. No wiring under the passenger seat. I can remove the passenger seat without detaching any wiring. Just four Torx 8mm bolts.Ah, okay. It's been most of a year since I was reading about all that and ordering my van. I remembered Orton talked about making sure he didn't get airbags but no details - my memory isn't too clear anymore...!
Since I do not like all the electronic doodads, the van was ordered with as few as possible.
