then it cant show both, it can only show either the analog signal on the 6y5 style digital tach OR the digital signal on the nema buss.
thats the pourpose of the small pink wire with white connectors taped at the engine harness, it splits the signal.
you can either get a digital signal for the buss or an analog signal for the 6y5 package.
