The Viper alarm that you buy must have a Kill Switch module and then it will connect to the current kill switch and manage both with just the Viper Remote. Make sure that whomever installs it is Viper alarmed certified. Personally I think Clifford is a better alarm.Also when getting it installed make sure they place the module in a hidden location and not under the hood. Thieves know that if it is under the hood they can short it out or by pass it and then steal your car. I have had my integra broken into 3 times, but never stolen. They can never bypass the hidden kill switch or module.
