Originally posted by TFR I have remote engine start and remote "busina" to keep those pesky people from leaning on my car. auto start is done by adding relay to one of the channel(viper 900 has 16 channels) One channel to turn on the ignition and one channel to crank the engine. I paid P500 10 years ago labor and materials.. You can add trunk opener, power windows roll up or roll down. or anything you might want to control as long as it is motorized. The power windows roll up functions everytime you arm the system. That means you are always sure that youre windows are rolled up when you arm. My problem now is the remote. Basag na casing. Sulit talaga. Tipid pa sa batt. san kaya makakabili ito?
