How would I go about wiring in an analog tachometer. Of course, red-12 volt, black-ground. Where would I connect the green wire?

It depends on your setup whether carb or computer

It's a 2008 Corvette motor. Fuel injected. Set up in a 64 custom frame restoration.

Your green wire is going to connect to the port on your ECU that controls the DIS firing. I would recommend that you re-post this topic in the C5/C6 technical forums with the serial # of the ECU that you're using to control your LS3. I'm sure that someone has resolved this problem before.

Good Luck!
