hey, basically I am making a modular circuit, where at any time there can be three different data inputs. I need some sort of circuit to only allow the flow of one of these data pins at a time. I'm super stuck please help

Thanks!!

How do you want to select between the 3 inputs?

ultimately it doesn't matter as long as only one wire is outputting

That's pretty vague.

You could use a jumper, rotary switch, or multiplexer. If only one input was active at a time, you could use an OR or NOR gate.
