Hi James...
since I wire up machines all the time I'm less afraid of the wiring job than the scatchy alarm systems.
But I might go with an alarm system for the glas break and motion goodies..they have to have improved a little since my last Viper.
The remote start is not something I would like anyways because I don't believe in extended idling of a cold engine. I usually wait the 30 or seconds it takes for the RPMs to drop from start enriched and then drive with a light foot until she's ready to roll.
