I cannot find the check engine light on my 1993 300ce (104.992 / 124-052) 124,000 miles. After removing the instrument cluster and following the wires 1,2,3,4,5,etc. I cannot find #1 wire, and in the bottom right corner of the cluster there is a location for a bulb but check engine is not written anywhere on the cluster. any Ideas, wires appear to not have been disturbed. any pictures of 1993 300 ce cluster out there?
