It’s been a while since I did any real circuit design… I am trying to plan out a circuit by which I have a load (LED A) and the lines going to and from it divert to some open leads.
If I were to connect a device that had another load (LED B) and mating connectors, the current would completely divert to B without a physical switch.
The diagram is simplified (obviously)… but all required electronics to ensure proper voltage etc is supplied to either of the loads is already handled on a logic board. I just want to sort of tap into the wires going to the load and create this plug-in overriding LED, basically.
Despite your not noting any current limiting resistors for LED protection, connecting another LED will not ‘divert’ the voltage/current from the ‘LED A’ unless you use some sort of circuit - I personally would use a headphone jack that disconnects the speakers and substitutes the headphone circuit.

just google ‘headphone jack socket’
Nice. Elegant solution. Thank you. All the limiting resistors are on a logic board. I wanted to hijack the current going from the control board to the existing LED (via wires) to divert it to another LED. This’ll work.
@Dan, I had no complete preliminary design. I needed an initial advice to even see a direction for which to march.
