It's a control unit of some kind. Not native to the car -- something that's been retrofitted.

Looks like perhaps having to do with the HVAC system?

Strange that is has a MB Part-Number though....
What is a "HVAC System" ? It to use the fumes of gas and and put it into the engine for burning it?

HVAC = heating, ventilation, air conditioning

Gemel manufactures theft alarms, are you sure that's not the siren...

There you go, it's a control unit for an alarm/immobilizer that was retrofitted from a later model MB.

Interessting, wasn't aware the car has Alarm..... haha.
i better plug the siren off then until alls is put together again.

I have a small red push-button left near the light-switch, could it be possible it is part of the anti-theft system?
I'll do some pics better...
