I believe it should go from the coil - to the tachometer. Pin #2?

Would that explain why my positive wire from electronic ignition is smoking every time I crank?

Smoking wire was pinching wire under cap. So can I bypass the harness to the gray coil wire?

Ayuh,... Ya won't have a Tach, til ya do, or repair the connection somehow,...

Just by-pass the cannon plug for the tach,...
