Drivers Warning Alarm in 1999 Beaver Marquis

This is a very specific question so it just might be that the answer may not be available so I understand that. My specific coach is a 1999 Beaver Marquis. I'd like to know if another owner of this coach or perhaps a model year or 2 older or newer knows where the audible alarm is. I don't get any audible alarms so I am guessing that the previous owner unplugged it. I guess its easier to find when its making noise than when its unplugged. Specifically it would seem to me that it would make a sound when my levelers are down and I start the engine, but I only get the dash light. Anybody out there with this coach? Thanks! Mike
