Hey man, i got the Viper 800 ESP and i got 2 door lock actuators, so now i got power door locks, and this thing comes with a shit load of sensors, including a hood sensor, so if anyone opens your hood, or anything, it will go off. I set my sensitivity a little High, but with the dual shock sensor, it does not go off by loud stereo systems or exhausts, but if you lean on the car it will start blaring! I got the hook up from one of my friends who got it for me at 350 installed! Well, get a god deal, and the Viper is the WAY TO GO!
