Hi all! Wondering if it is possible yet, through modding, to add electrical input (The white box when you hold a wire tool and look at them) that would allow a cable to be attached to say a large storage box for example? It would need to be able to be powered, check the input power level, etc.

Is there a way to do this?

I think the little white box is client side.  But you could parent an electric object to the storage box and do stuff with that.  Like add a switch to the box and only let the box be opened if the switch is on and powered.
