thank you

Answer
In the wire harness running to the driver's door there is a light green/orange wire that disarms the factory alarm when you unlock the driver's door with a key.  This wire sees a ground when unlocking the driver's door, if you put this wire to a ground it should disable the factory alarm.

To my knowledge though the alarm is just a noise maker and does not shut down the vehicle.
