My printed circuit burned the trace going to lower right connector pin 2 "Masse" or ground.
The 5th pin from left reads masse as well but has a differnt color wire as pictured.
This resulted in my cluster lights going out. I am supicious of the dimmer potentiometer and the cluster connector wiring. I changed the blue black wires on the pot to go to the lower connector as they were on the upper when I got the car with non-working circuit card.
Should pins 2 and 5 from left on the right cluster connector both be brown wires as the wire is in pin 2 pictured.
Sorry, first post so will just throw some pics up.
