  1. Sam, as much as we would like to help you, not all car alarms are installed the same way. Different brands and different setups will call for different wiring. Our advice is to take your car to a qualified alarm installer and ask them to re-program your remote to your car alarm because it does take some wiring knowledge and experience to know what to do. Hope this helps. Good luck on your 1996 GMC Sierra alarm troubleshooting.

  2. dear sir, i own a 1996 gmc sierra and my remote is bad. i can’t turn my alarm off or on without the remote. i don’t know how to disconnect the alarm. is it a way to disconnect the alarm beside disconnecting the battery?
