hey guys, i was just wondering, if our cars came from factory, ready to have the anti-theft system installed. i ask this because i saw an anti-theft control module for sale, and it's from 94-98 stangs, so maybe i could install it. i have a 94 cobra, and i know for a fact it was an option, but i know i don't have it(in the trunk, i just have the keyless module, what's the other open plug back there?)but i need any alarm, so i was gonna give it a shot. any ideas??
