I got to spend some more time on it. Wiggled every cable under the hood that I could find and cannot reproduce the dead gauge cluster that says 'no bus'. So I started to take apart the dash and 'no bus' returned for a few seconds but went away and I could not make the problem happen again.
So I pulled the gauge cluster out and reinstalled. Now the speedometer is stuck at 120. I drove the truck about 10 feet in reverse, and 10 forward and it stayed at 120. I pulled the cluster back out and put it back that didn't help either. Anyone seen this or know what I should try?
And as to the original problem of the dead gauge cluster after hitting up a bump (hitting another bump fixes it for a while), if there are any other suggestions they would be greatly appreciated.
