I forgot that the AC panel has two bulbs so the grey wire may be for the second one . I don't have AC either but I did a search and the power wire for the heater
panel and AC lights plugs into the fuse panel. If your heater panel light is working then you should have that wire and the one in question is probably for the other light.

See the diagram. Check the blue arrows.
