digital tach on 115 quit working

[Hollybrooke]

Have 2013 115 yamaha 4 stroke. Single binnacle control. I put a half tower on my boat and took out the single control and added dual station morse controls.
Now the digital tach doesn't work.

The only wires I cut (as far as I know) were for the trim switch. It was a red/blue/green and I ran a new trim switch and it works. All the wiring harnesses coming from the tach appear to be attached and I have yet to find any loose or unconnected wires. Anyone have any ideas why the digital tach quit working?

There is a green wire for the tachometer signal and a green wire for the down trim circuit. Perhaps the wrong green wire was cut.

Does the trim and tilt work as designed?

Thanks for the schematic, the trim works as it should. I'll check the green wire from the tach when I get home.
