The trad. 70s Lucas electronic Tacho is connected in *series* with the
coil. So it requires that the connection between the coil and the points
is routed *via* the tach. So you need two wires for this. The standard
connectors at the tach are such that it is easy to connect them should you
ever need to remove the tach for servicing etc. Failing to do that will
cut the ignition if you remove the tach.
In addition to these two wires, you need a supply and ground wire, as you
noted. Plus a wire to the instrument lighting, of course.

They will usually connect as you have noted, with ONE wire to the coil.
