'95, I don't think they did. Factory alarms didnt really come around until recently and even then, Honestly, They suck. I remember on one my grandfather bought new in '95 shortly before he checked out of this hotel called life it had a key fob with a little flashlight that he had to plug into a port under the dash in order to start the truck and once started he could remove it. Don't remember what it was called, I was like 10 or so at the time.
