I made it real simple...removed the bulb from the DIC during my stereo install. When I adjust the steering wheel to my liking, I can't see the seatbelt light either. Will remove that bulb soon, too, as I tend to know whether my seatbelt is on and don't need the car's guidance in this area.
Ditched the TPMS sensors too. Since refusing to cater to the whims of all these stupid failing sensors, all my DIC says anymore is FULL ENGINE POWER!
