My 89 3.2 has the factory alarm, horn honks if you happen to set it off. Turns on by locking the driver door with a key. You then have to use the key to turn it off by unlocking it. If you happen to not shut the driver door fully and move the door, the alarm goes off. Honestly I cannot remember how to turn it off but I think I had to insert the key into the door and turn it to the right. The first time I set it off, I had to remove the battery cable to shut it up.
