depends on what you want the alarm to do for you, and for things like dome light surveillance, door locks, hord, parking lights, and remote start, you're going to have to know how to wire relays, and have several handy. You'll also have the fun of taking apart your dash and steering column, which usually requires special tools for the steering column, and you'll usually have to hunt for some of the wiring like the door lock/unlock wires. If you're really lucky, a site like the12volt.com will have all the data you need for the door locks and wiring color codes.
