TACH/Annunciator Ring issues

2004 Ridgeback 107" I don't want to start throwing parts at it yet. The annunciator ring/TACH does not work, haven't had a tach for a year now. Already completed the wire-plus mod, thought, maybe the wire-plus would fix the issue.....it did not. What wire/color wire sends the signal to the annunciator ring? I know the signal comes out of the ICM, after that I'm dumb-founded. I do not have a wiring schematic and the ones that were on this site have been deleted. Any help would be appreciated.
