In addition to what Roeland posted above.
If you get stuck....check out the relevant Wiki pages, quests, maps, videos, guides, walkthroughs & hidden gifts/bonuses
I personally find it much easier to consult, study & follow the maps in certain types of scenarios instead of the videos.
What you need to do ... is look at the maps that I have linked you to below ... you need to zoom in on the maps so you can see which way the cables are going so you can connect them properly .
You should also zoom in on your game scene / mine you are working on in order to see which direction the wires are going to connect them properly..
It's a puzzle you need to look really hard and where you place the electrical boxes.
The wires on the electrical boxes should match the wires that are in the game scene / mine.
The conveyor belt will not work until you put all the electrical boxes in the correct positions.
