The black wire from the engine harness goes to the smaller post on the starter. This is the engine start wire from the diagnostic connector. There should be another (maybe blue) wire that connects to the same post. This is ignition start, which triggers the stater solenoid.

Your starter relay should be near the steering column and is usually orange. I do not know what you have in your hand. It does not look like an OEM relay harness because BMW do not use black electrical tape and looks like its already seem some heat and possibly melted.

I suggest you have an auto electrician inspect your wiring.

The fatter of the two smaller wires goes on the bottom terminal. SKinnier one can go on the top.

Skinnier one is unloader relay ground, and the other one is the starter signal
