I just did this a week ago in my 2014 JKUR without side airbags .
I had the airbag light on constantly, drove it like that for two days...... Reinstalled seat and plugged in seat sensor, airbag light went away.
I had my battery disconnected for my compressor install after I reinstalled the seat so this May or may not have helped reset the light.
Ordered 3/22 Billet JKUR, Auto, Connectivity, 4.10 gears, Painted top and Painted fenders.
RK X-Factor 2.5, Bilstein 5100's, Fox ATS dampener,
Spydertrax wheel spacers, Rockhard engine & transfer case skids, F&R lower control arm skids.
