MB experts,

I have a 2002 e320 wagon 4matic. I have a problem where my lights for my dials do not come on when I turn on the headlights. All of those lights went out at the same time. Changed bulbs and fuses and still no luck. Looking for a schematic of the pins in the two harnesses that connect to the instrument cluster so I can try to determine if the problem is in the cluster or elsewhere. Thanks in advance.
