What's in the box behind the fuses - W124?

Can anyone tell me what lives in the box behind the main fuses in a 1990 300 Petrol.

The one with around four screws, it seems to be all one piece with the fuse tray.

Thanks in advance,

Paul

Thanks for the info.

I've been looking for the FPR, looks like it'll be there.

Cheers,

From memory ( it has been a couple of years since I last had a W124 ) I don't think the FPR relay is in there , but I might be wrong .

You will find a big long one with part no starting 126 - this is the bulb control relay and contains the bulb monitoring circuitry . There is also a cigarrette packet sized one - part no starting 201 - this is the flasher relay which also controls the heated rear window .
