I've heard of Viper alarms, they're a good company. Sounds like a really cool alarm, i bet it calls your cell phone if someone is breaking in too.

The Alarm kit usually consists of radio receiver, wires that you splice into your starter, ignition and depending on manual/auto trans a neutral safety switch as well as random stuff like dome lights door locks and so forth. If you have a good wiring diagram for your vehicle then its just as easy as splicing into specific wires on cars wiring harness when alarm manual calls for it. Most of the kits even have cool specialty splicing caps that you pinch onto existing car harness and they stab through the rubberized coating and pinch into your factory wires, so you don't have to cut and hack.
