My Tach, oil press, and temp guage are not working. The dealear told me it was that the plug on the female side of the connector to the cluster was fatigued from diesel vibration and they could fix it for $3000 with a new harness. I have tried several fixes including slightly bending the male tabs to make better contact and also placeing flat pieces of solder in the connections. Each time I fix it it stops working almost exaclty five days later. Could there be a computer problem ie a problem with the signal and not the connection?
