The box will have to release a spark when the terminal with the arrow is shorted to the housing of the box (GND). Regardless of the condition of the points. The points are a switch, one side at GND, the other side goes to this terminal.

The other terminal on the other side goes to the coil primary. Be careful, there can be HV present even when there is no spark.

And as you said correctly, the center wire is +12V switched by the ignition. And GND goes to the spade on the housing.
