This post shows the solutions of the Plug puzzle/Junction puzzles I’ve encountered in the game so far. As I encounter more, I’ll post pictures of them here. Hopefully you’ll find the one you’re looking for. You can also check out my youtube playlist of all puzzles I’ve solved so far.
Circuit Puzzle Solutions here.
The goal of the plug puzzle is to fill the meter up to between the two blue lit pieces. While these can be solved through trial and error (how i solved them), there are good videos on youtube explaining the math behind how to know what lines and what paths to follow if you want to understand the “why it’s 8 when i go through this way”.
Make sure the dials and the switches are all turned like they are in the photos as well.
These are all sorted by the amount the meter needs to fill up and how many plugs there are in the puzzle (# nodes, # plugs), so it should be easy to find the one you’re looking for.

The cords were hard to see in this one, so i added #s to tell where the 1s and 2s were each plugged into.

Just use the 1s.
