Notice the one pictured does not REMOVE the points from the coil. A true electronic switching igntion, the points are removed from the coil and go to the box, then the box goes to the coil. This is likely no more than a diode or cap or something in there and likely doesn't do much of anything.
On a side note, the problem with any of the points--triggering-a-box setups is that the points now have such little current going through them that they can lose conductivity from?? fumes/ oil/ etc and then not trigger. This is not a "big" problem, but it can / did happen
