Show us an image of the back of the pCB.
It may also help to know which chip is under the label "Modul Nr. 40018" as knowing where the chip's ground pin is helps identifying the trace to the wire pad.

Good chance that the negative sign (-) on the electrolytic capacitor will be the negative rail.

It's the can looking device between D3 and R8.

Nice clear photo of the reverse side of the board would help also.
