Just ignore the grey wire. Put some electrical tape on the end so it doesn't short against anything, and push it out of the way.
What you described (the dash lights lighting) is normal. It doesn't indicate a malfunction. It's just a wire that you don't need. It was used to light the little dial on older radios, but newer radios don't use it.

> When I put a known 12 volt supply to the Grey wire the dash lights all light. would that indicate that the light switch needs to be replaced or that the grey wire needs to be attached to something?
