Just a way to have a wire on two different entities that can be connected/disconnected through the logic system.
Basically you have 2 "wire couplers" that when you bring close enough together will attach to each other. And it will connect an input wire to the output on the other coupler.
You can then disable the coupler (so it won't connect at all), or disconnect the coupler using a boolean.
This would allow a lot of modular wire systems, basically allowing us to plug in new systems to an existing circuit.
I also made a very rough drawing of how this would function.
