I never heard the buzzer before today,  it didn't work, I thought it had already been unhooked. Today I open the door and hear a faint buzz, the key is in the ignition but it's in the off position. I get to looking around and find the buzz is coming from the buzzer unit at the fuse box. I did notice that the seat belt light started acting different in the last few days,  instead of it going on and staying on for a short time it would flash erratically.  Even when the key is out of the ignition the buzzer is sounding,  faint but it's going off. I unplugged the I/P harness assembly wire and now I have no faint buzz. First thing I'd like to know will this cause any problems not being hooked up,  if not the next thing I'd like to know is it better to unhook it at the top single wire from the buzzer that plugs into the fuse box ? I looked for the top wire from the buzzer to the fuse box but I can't seem to recognize wich one it is,  and I can't feel a wire coming out of the top of the buzzer that goes to the fuse box.

Got it completely out,  unplugged from the fuse box and all. Single wire on top off buzzer has a  dark orange or brown color plug.
