I installed an AutoMate (made by Directed Electonics aka Viper) keyless entry add on alarm system with two sirens, horn honk, dual zone radar sensor, digital tilt sensor, dual impact sensor, hood/trunk pin switches, ignition disabler, window module to roll up the windows and I utilized the EXT output to vent/open the sunroof...all off the factory remote!! I also connected the pk lt output to the headlights instead due to the fact that the factory keyless already flashes the pk lts plus it draws alot more attention at night. It works great and adds REAL security to the factory setup.
There have been some comments about the knee airbag being in the way of the ignition wires. Here's a clue to make life easier. The access panel to the left of the st wheel will give you access to the top of the fuse block. All of the ignition harness wires are located here, as well as most of the other alarm wires. No need to remove the knee airbag.
Mount the sensors under the center console. This will allow for equal sensitivity of the sensors around the entire vehicle. Also, there is a plethora of room behind the glove box to mount the brain/relays. You'll have to extend the wires from the driver's side, but it makes for a much cleaner install (no rats nest under the dash) and will slow down a thief, making him search for the brain in order to bypass it. Just make sure you tape up your extended harness and run it with the factory harnesses to conceal it as well as possible. Remember, an security system is only as good as it's installation. The more time it takes a thief to find it, the less likely he'll stick around to finish the job.
Hope this helps!!
