1991 300E headlights & parking lights
 

Hello,
I have a 1991 300E. Bot the headlights, and the side corner lights do not work. Also, the turn signal lights do not work.
They used to be fine until I removed the Instrument Cluster.
I have read books and went into forums but could not find a scenario that could lead me where could be the underlying problem. I do not see fuses, relays, or control unit for the circuit/s involved. It could be a ground wire but I do not know either how to even start with it. Can anyone please direct me? Thank you so kindly.
