Ok, I've poured over a ton of posts & comments, but no confirmed answer.
I pulled the seats, carpet, seat belts out of my 2016jku, I spliced the black and green seat belt wires for driver side, that fixed the seatbelt light. I have read that splicing the LTblue w/white to the LTblue w/purple on passenger side may fix it (I did not try this yet). I do not have the factory seats any longer and didn't retain any sensors, clips or plugs off the factory seats. I did not have side air bags to start.
Any help is appreciated.
