2005 FL 120 Dash died
 

My dash is dead. Starts normally, runs just fine, etc. but no cycling of the dash instruments with the key on, and all are pegged at "0" after start-up. My ScanGaugeD gives me the temps, voltage, etc. Might be coincidental but I also have a "254 12 0" code which points to a fuel sensor or some such. The fuel filter glass dome is pegged at the top so that might be the reason for that code.

The MMDC box photo is attached and it does not look happy. An online search suggested that this is a common fault and the elec connectors on the MMDC could be corroded as well as the connectors running to all the other instrument gauges.

The truck lives in a hot and humid swamp and, has not been run in the last several months. I normally am on the road every 3 months or so the truck is mad at me?

Any help will be appreciated.
