The key in ignition alarms keeps going. Driving down the road, it keeps beeping. Well, it's a steady tone. Where is that puppy. I can hear it but only one ear works very good so I can't seem to find it. I can live without it, Is it a plug in unit or what? I suspect this is what is draining my battery too.

 

on my 99 it is in the BCM behind the ash tray at the bottom middle of dash.
