Once this winter it died for about two weeks then came back-no problems until a few days ago when it died again.  No sign of life yet.....is there a ground in the instrument cluster that I should check, or is the supply signal the more likely culprit?  I guess my initial thought is the signal is more likely as I never had this problem before the the 3B conversion....

As you mention supply signal, I presume the dash is digital. Mine had a 
similar problem, which turned out to be the mechanical part of the 
sender unit had the shaft corroded. Difference being, that mine didn't 
read correct speed when and if it came on. If yours reads the speed 
correctly when is on, I would suspect the wiring and connections.
