They aren't that difficult, you just need your vehicles wiring schematic and the instructions with the remote starter. I put one in my old 4Runner and proceeded to hook up a wire wrong. After figuring out the problem I got it to work fine. That was nice to have in the winter. Just be careful if you're working on the vehicle, you don't want the remote in your pocket where you could bump it and cause the vehicle to fire up.
