Pin Out wiring
Does anyone now how to feed 12V power to the cluster, on the bench, so it will light up all/most of the lights? Mine is out of a 1993 400SEL and has the round socket connectors like the picture. I have all 4 female plugs that I can feed power through. I just need to know which wires on the plugs to join connect to 12V. Thanks

Correct. What I would do is connect your grounds and your battery supply direct to cluster and all the ignition supplies via a switch. That way you can simulate the ignition switch on the bench..
