You can ground the factroy alarm disarm wire and keep the factory alarm from going off. There is a light green wire in the door boot that will show positive current. If you have a test light, ground it, Strip back the coating on the light green wire, make the factory alarm sound and touch the test light to the light green wire. This should disarm the alarm. If that happens you can simply make you a ground right there behind the kick panel and ground the wire out to keep it from activating. I have seen this done many times and it has worked numerous occasions.
