240 connector std 7614.4 365060-1

Hi everyone,
I've got an European 1992 240 B200 M47 left hand drive.
Under the steering wheel I have a white 4 pins connector with this reference on it "std 7614.4 365060-1", connected to...nothing.
Everything is working in the car except seatbelt warning light and no relay/buzzer sound. Not sure if seats heating works. The light of the switches comes on but I don't care about it for the moment.

I join a picture for better understanding.

That should be for the optional rear speakers

Ooohh yes !!! I didn't even think about it. I thought : with these colours it should be something on right and left, but my turn signal are working. So maybe seats... heating...belt... Nooo SPEAKERS !!! Shame on me.
Thank you for your help again !
