Ed, 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 remove your car alarm because it does take some wiring knowledge and experience to know what to do. Hope this helps. Good luck on your 1999 Chevrolet S-10 Blazer car alarm removal.
