C100 connector and the tach wire on digital dashes

[chris]

Does anyone know if the white tach wire continues into the passenger compartment from the C100 connector. Or will I need to run a separate wire for that.

I believe the only place to get tach is on the drivers side valve cover Green plug
I just grabbed the harness of the floor from my digital dash and see white wires but I have no clue where it would land inside, and the wiring diagram with digital dash dose not show it
