blue alarm box under the dash

on my car there is, what i assume to be, a seat belt or door ajar alarm box under the dash behind where the radio is. My question is. dose this thing have any other important fuction or can I just unplug it and toss it? It will start dinging while Im driving sometimes (seat belt on) and it gets on my nerves. i was thinking I could use the weight reduction lol. maybe an ounce worth of reduction lol.
 
air bag monitor? when i open my door it chimes through the little box.


If you are talking about the Blue Box behind the Climate Controls it is the Airbag Diagnostic Monitor, it should not be making Chimes when you open the door!
