What kind of kill switch? Alarms come standard with a starter-kill. Most alarms these days have 2-way LCD remotes that work within a 1/4 mile and will beep if the alarm goes off. It also lets you know the system is armed, disarmed, running, etc... Depends on your budget and something like this should be bought and installed locally.
the main thing is the install. The main things I do as a min. is alarm with a 2-way pager, an interior siren, back-up battery, and a digital tilt sensor if you have rims.
Trucks make it easy to cut the wire power so the battery
an interior siren for the stereo
and the tilt for rims
extra siren(s) are nice
