Is it possible? I took cluster out and looking through opening where check engine bulb should be do not see any lettering. Just red plastic with no labeling saying "check engine". There was no bulb in there so I put new bulb into that right side opening and it did not light up with key in run posittion. My car is 92 500sel with digital trip and milage counters. Please help.
