What is required to get wind vectors on IFD?

Wind Vector datablock operates on pure dynamic data, regardless of what's entered in the Air Data Calculator. The Air Data Calculator items will get populated via the air data source - note the green-colored parameters as the air data sourced items.

In the examples below, I set the HDG to 280 in the Air Data Calculator resulting in a non-calm Wind Vector. The Wind Vector datablock never changed. When I set it back to the sourced data, the Wind Vector shows calm.
