How does your 2002 jeep grand Cherokee limited remote car starter work and why does the alarm sound when you remote start the car?

The alarm sounds because when it was installed they did not hook up factory alarm disarm. This is crucial because when the car is remote started, the car thinks someone broke in through the window and it trying to start the car while the car is still armed. If the disarm wire is pulsed the car then sees that whoever is trying to start the car wanted it disarmed and allows it so the car doesn't think it's being robbed. On most directed electronic alarms it's a Light Green/Black wire comming from the brain for Factory Alarm Disarm
