CDI signal or feedback signal from coil?
Loren is an expert in this arena, so I would ask for his opinion.

Okay, I'm looking at the factory wiring diagram for my car and I have no idea where the tach signal comes from.
The tach signal is the purple and black line on the diagram below:
According to the factory manual, "1" indicates "on coil, to primary distributor lead." However, it also connects to "terminal C" on the CDI unit (N15). The coil is "N". "T2" is "Cable Connector, Double".
I have no clue where that purple and black wire goes. Is the switch supposed to be the points?
Also - I picked up a pair of terminal clamps and a DC momentary switch today so that I can put together a simple remote starter switch (so that I can pull all the plugs and check the spark while cranking the engine).
