Ok well I have a 91 Hatch DX and here is how I fixed mine I UNPLUGGED all those BEEPING sounds cause I mean c'mon its common sense to put your seat belt on when you get in any vehicle....Just sounds silly to me to even have them and as far as the beeping sound for your lights I would not know cause I dont have one it was that way when I bought the car so who knows....there is a plug under one of seats like some of these people have explained and there is a plug where your rear view mirror is if it is like mine...GOOD LUCK!!!
