I pulled my instrument cluster out for inspection. Previously I said the plug in back had been replaced. I rotated the plug one pin CCW and plugged it back in. The gas, oil and water temp gauges stopped working. However, the dash lights started glowing and the low fuel warning light came on. This had never worked before. I think the MB shop that put the new plug in may have mixed a couple wires.

Does anyone have a schematic of the plug cluster? If I knew what each pin was for I could fix it myself.

Thanks,
