Sure thing! When installing your Greddy (copy) tachometer on your L300 FB with a 4N14 engine, you'll want to tap into the alternator's signal wire. Locate the alternator, and look for a single wire that carries the RPM signal. Tap into that wire for your tachometer connection. It's typically a thin wire coming out of the alternator, and you should be good to go once you've made that connection. Easy peasy! If you run into any issues, feel free to reach out. Happy modding!![]()
