I had an aftermarket alarm that the previous owner didn't tell me about. I ended up yanking wires out of the siren thing, then unplugging the horns. Later I got the Mazda mechanics to let my horn work. There was also a silver box that ticked, I think it was like a vibration sensor or something. I was working on the engine and couldn't stand the ticking, so I yanked it out and smashed it with a hammer. I through out the damn siren thing, and I have yet to follow the wire into my firewall to see where it goes.

 

thats what i do with aftermarket alarms, hammer time
