C280 MAF CABLE URGENT HELP PLEASE

Hi all.

I bought a C280 - 1994 a few weeks ago - I dont know what the owner have done with the car before me, but the MAF cable is plugged with wires strangly into some kind of ECU box...

Can anyone please tell me or/and take pictures of where the MAF cable should be plugged in? The one end of course into the MAF it self, but its the other end i dont know... my car has very rough IDLE at this time and stalls very much. When i disconnect the MAF it runs "ok" dont stall or have rough IDLE - i just bought a new MAF and new MAF cable - but as i said, when i bought the car the owner before me had done some kind of "homemade" plug directe into the wire of a ECU job....

I can take pictures later today, but can anyone please take some pictures an tell me where the MAF should be plugged in on this car..

Thanks a bounch everyone!
