A grand for parts and labor. Those sensors are spendy, like 60 bucks each including labor. That was all my original plan. I got a new one though. The only sensors I would get would be door sensors and window sensors. Because they have to open a door or break a window to steal things. The rest of the sensors are just ways to get your alarm set off. And window and stereo controll is hella tight, along with remote starting. You could probably ditch like half the sensors and save a couple hundred. The window controll up and down (up when you arm it, down when you dis-arm it) costs 80 for going up, 220 for going down. The wiring is a bitch I have heard.
