They're plugs and cables, if you don't understand the concept, this probably isn't the type of save for you
@goglesq, that's what I mean. It isn't obvious where the connections are supposed to go, because you have to use arrow keys and image flipping to get it right, but it isn't explained where the connections go
Flipping (Shift+R) or rotating (R) may also be needed
@R33sesK1ng everything is meant to aline fine, you may need to use arrow keys while placing to get it aligned as it should be.
The outlets don't line up with the inlets. I don't understand exactly how this is supposed to work without proper connections
