to be honest if I want your car I'll break into your house find the keys and drive off.. no amount of wiring things stops that if I have the remote. now if the alarm has a hidden switch that works in conjunction with the remote then its probably going to slow me down a bit. (autowatch do this.) now if I dont really care I'll key the crap out of it and trash the thing as a I can't get it so you are going to have it payback.
key point here. insurance. if someone wants your car bad enough it will disappear. all an alarm will do is slow them down.
troy,
