no I didn't cut any wire to the alarm did't even touch it just lost poer to the battery of the car.dave25456

now I was checking all the wires again today and saw a red wire that is hanging now that red wire is connected to the alarm and splits and one wire is hanging near the radio harnes lose and the other is running switch in the glove box.Also the locks and the unlock works and the siren is still working the only problem is the light stays on and the alarm doesn't active when u open the door.dave25456
