malfunctioning alarm system

[RonK]

My 91' 300sl has started sounding the alarm (horn and lights) without reason, which has not endeared me with my neighbors. How do I disarm the alarm system permanently? Thought the unit was under the passengers side floorboard. I disconnected two black pins to what I thought was the unit - it wasn't. Called a MB mechanic I use at home and he said the unit was located under the hood. I looked where he said and couldn't find it ( said it would be labeled Becker). Can anyone help or offer any suggestions? Thanks so much.

The alarm module is in the trunk and is mounted above the battery (picture).
