You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
Keep input wiring and output wiring separated.
We strongly advise labeling the wiring to all devices in the system.
