Car Alarms: 96 Buick Riviera Factory Alarm, black widow alarm, buick riviera

Question
Hi, can you please help me?  I am having problems with my factory alarm.  It keeps going off for no apparent reason.  I had the Black Widow alarm recently installed but my factory alarm is still enable.  Can you tell me a way I can disable it?

Answer
Did the factory alarm go off prior to having the new system installed?  If it did not, I would have the installer make sure they tied into the green wire by the battery under the rear seat.  This wire serves as the factory alarm disarm wire.  When this wire sees a ground it will disarm the factory alarm.
