how do i go about testing the factory alarm in my 87 300e? ive never had it go off so i want to see if its still operational.
also, im planning on having a viper alarm installed due to expensive audio system. can the factory alarm continue to work as a backup. ( extra noise and more wires to cut)
will it interfear with the viper alarm?
