what's happenin folks? i bought my first truck, but i wanted one so bad i decided to to get it slightly cheaper without electric. now i want to get a nice fancy alarm system, but to have the one i want installed with being converted to electric locks is WAY too much. so i was thinking i'd do things in phases. starting with the lock actuators, then the alarm from the manufacture to save some money then the only thing i pay extra is for the labor of the install. question i have is do all silverados come pre wired for the alarm? or will i have to do a little extra for that as well? i have a 2009 silverado
