I had an alarm fitted to my 90 model 4runner AFTER the window was smashed and a whole heap of stuff stolen out of it :pat: Went for the first alarm i could find. Can't remember off the top of my head what brand it is think it might have been Vision. But well I live on a main road and every time a truck goes past the vibration makes the door open warning buzzer go off which is annoying during the night and i washed out my engine bay after being in the mud and got water in the tweeter and the alarm didn't sound for two days until it dried out. Sounded like a strangled bird !
