Fitting instruments to my RIB

[57paulimo]

I'm trying to fit trim/tilt, oil pressure and Tacho gauges to my RIB.
The engine is a 70hp Yamaha 3 cylinder BETO.
I downloaded the wiring diagrams and think I've sorted the wiring for the tilt/ trim and oil pressure but can't find any info on the Tacho wiring but assume the signal is from the CDI unit???
Any help would be most appreciated.

Assume you have 703 side mount. There is a short harness coming out back of control box about a foot long. Yellow is 12volt +. Black is ground. Green is signal on your tacho. Put a fuse in the yellow feed.
