I have an 06 C6:
Best place to get tach is on the passenger side coil packs off the main connector. It should be a green wire. The wire will be either solid green or green with a white tracer.
Mine was green with white dash setting 1 on Nitrous outlet WOT/WS
Its in the middle you can disconect it to make the connection.
TPS comes right off the side of the TB connection on pass side the green wire, I tapped into it a few inches back so the connection is under the fuel rail cover.
Have not tested that on yet, but the setup worked.

Can I run the white tach lead from a MSD window switch to the green tach wire described in above illustration? Where does the green wire originate under the passenger fuel rail? Is it one of the seven wires in the main connection you circled in green under the fuel rail? Thanks so much for you help and patience...
