I have an old Force car alarm that still has the shock sensor, brain, wiring harness, one remote, an LED, and the siren. It worked when I removed it about ten years ago(not kidding). I found it today but I don't have the instructions for it and would like to use it. I'm sure that the basic car alarm hasn't changed that much in the last ten years so it can't be much different than a new one. I hope someone can help. Thanks! James
