I removed the cluster and measured the voltage at the two connectors. The first picture show the measurement of the left connector, the second picture for the right connector:
Left connector has power only at pin C1 (11.6 V) and pin L2 (7.47V) and that is suspicious too few pins.
Right connector has power at pin A6, 8, 9, 11 and B3.
Can someone interprete the measurement, is power missing at some pin? especially of the left connector?
The minus "-" sign at the pins means 0.0 V was measured, probably ground.
