One "general" way to tell is to look at the + side of
the coil.
If the engine is ballasted, there will be two wires on
the + side of the coil. One will be the running power
supply, it'll be about 6V, and will come from someplace
deep in the harness.
The other is the starting supply, it's easy to spot
because it comes from the solenoid. This is switched
by the solenoid to provide a full 12V for big sparks
at starting. This wire is, on a few cars I have seen
including mine, not part of any harness so it's
easy to see.
