tachometer install

I am trying to install the Twinscan dual tach ... it is the one with both
engines in the same display (no MPG though) ... kind of like

Anyway, the "official info" has no reference to where the engine pickup is

Yamaha tells me it is the green wire coming from the wiring bundle (which
terminates behind the engine switch)that terminates behind the switch at the
helm. However, this doesn't seem to be it. I read Dan Hofmann's message of June
4, 2000, and it appears that he used the 'green and white" that is inside the
grey cover on the side of the engine ... I'll give that a try

If that works, I will run a wire from each engine to the tach

Does anyone know the pole settings that the Yahama uses? It is needed to
calibrate the tach

I tried the green wire coming out of the harness behind the helm, as will as the
engine green wire, the "green with white streaks" wire and the "white with green
streaks" wire. None of them gave me any RPM signal. I suppose it is *possible*
that the tach itself is bad, so I guess I will find another tach and
troubleshoot

The thing that has changed is that the current wire harness do have the Green
wire in them. I was on Ron & Susan McDaniels ( #36 -89 Tanah - Keeta) when he
installed his. He was able to pick up the green wire just as advertised. Neat
installations with both LED read outs in a round face

On mine I did have to use the green & white found on the engine itself
