Where is the factory alarm located at because i installed a remote starter and alarm on my 97 Bonneville. The thing is is that when i accidently hit my panic button on the factory keypad the horn, headlights/fog and the aftermarket alarm all comes on and i like that. So i was wondering is the a way so if i rewire the factory alarm so that when someone trys to get into my car that the factoryalarm sounds also?

Factory alarms are generally integrated into the cars computer, so they cannot be 'tapped' into.

so why doesnt mine work right?

The factory alarm is integrated into the Remote Accessory Control (RAC) module. It sounds like your aftermarket alarm is current sensing and triggers when it sees the drain of the headlights and horn. Your factory alarm should have a forced entry input fron the doors which trigger the factory alarm where as aftermarket units are typically triggered by the dome light wire.

I can't think of a way to integrate the two alarms
