As much as I love the presentation of having pdf manuals separate to the game, I really think it wasn't necessary here - I think it would be more fun if the symbols broke down into more logical progressions it would make the game more intuitive and I think this one lends itself to being figured out on the fly rather than a more slow and methodical approach.
That being said, I absolutely love the idea and the juice is on point - it felt so satisfying to patch things in and move the leads around, ripping them out and letting them fall, and the frantic network of wires you end up with lends itself well to the theme - the game's just as much about cable management as it is about figuring out the combinations!
Overall, an excellent submission, well done on getting it out!
