I installed viper vx791 car alarm in 95 sc300. My lock wire got messed up and was locking my doors when I was driving car. Now I have siren that has low audiable sound on all the time. Is the brain gone bad or there is short between siren output and wire with positive output on harness ? Is there wire that has 12 + on int all the time?

 

sounds like a bad ground or connection some where.
