Well, vereyone thinks that alarms are easy to do, just hook up some wires and there you go. I feel that there is more to it than that. First, an alarm is only as good as its installer, If its not put in well, it does you know good. A good portion of this prep work. Getting the alarm ready for the vehicle. Second Experiance makes all the differenc in the world. A good theif is going to get your rig if he wants it bad enough. All you can do is try to slow him down some. Instead of 15-20 seconds it takes him 5-10 minutes because he cant distinguish the alarm wires from the car wires or he vant find the brain or the power source is not accesible. There is more to it than hooking up some wirs. I have been doing this as a profesional for about 7 years and I feel that what I do is more than just hook up some wires.
Also, when you buy an alarm, buy one that will be easily replaceable. If you loose the remotes, or they quit working, you will be upset whan you cant buy your ZAPPER alarm remote down at the quicky mart. Get a national brand, VIPER or CLIFFORD or AVITAL or EXCALIBER.
this is all just my opinion, so take it as you will
