If my memory is correct, someone - maybe DougB - discovered that if your truck has the gauge, then there is no bulb in the cluster for the idiot light. Look in the manual to find where the bulb should be and see if there's a bulb in that socket.

I remember something about some tape blocking that socket also. Maybe Doug remembers.
