When I removed the round plug the D pin came broken from the cluster.
I then glued it to the connector in the same location according the the mark left on connector.
I then plugged it on the cluster. As it didn't not worked, latter I removed it from the cluster again and the D pin wasn't there again. Then my only chance was to plug it aligning the pins using as guide two pins that are spaced differently than others.
These two holes in the connector match with the two pins on the cluster. With power off I tried and the connector will go into the pins only if these two pins and holes are aligned. There are no other way to plug connector and cluster pins if these two holes and pins are not matching one with other. This is the way that I installed the cluster in place after the first time when I had trouble.
I really don't know why other parts of the car like radio, fuel and temperature gauge are not working after the first time.
I need help and I am willing to give all necessary details of the problem as I gave today.
Thanks
