I noticed another thread where you are having tach problems as well.
With that Cummins installed, are you using Ford sending units or Dodge sending units?
The two may not be compatable if you are using Dodge sending units and Ford gauges.

Ground problems, even under the dash are much more common with the newer trucks.
So much plastic in modern dash construction tends to isolate things like gauges from the required ground paths that it is a headache for every manufacturer.
Then on top of that, the bean counters have the engineers use the smallest possible wire size, which after a few years may or may not be able to carry the same load it did when it was new.
I still vote for a ground issue.
