I am looking for the location of the Anti Theft Module. By the Vin number this one was not shipped with the Alarm yet there is not an aftermarket one on here. Just did a large amount of work on it. Friday took it for a road test and the only thing I had left was to replace a frayed throttle cable. Well picking that up tomorrow. Monday went to unlock the door open it and the alarm goes off. Now I did not arm the alarm as there isn't supposed to be one. I have tried numerous ways of disarming the alarm and nothing. through all research and calling dealers they are as stumped as I and I need to know the location of the module. I also have a similar problem except the other one the alarm isn't going off so thatis something wrong with the ASR.
