As was already said, you can't do this on a wire-level. But you can do this on a VI-level when stepping through your code. You can set a property on a VI called Suspend When Called. When execution reaches the subVI, it will pause before continuing. You will have a chance to see the values on your input controls attached to the connector pane and update them before continuing execution. For instance, if you had a boolean input control that had a False value, you could toggle it to True and then unpause to continue.
This property is in the VI Properties dialog in the Execution section.
