Hi Glen,
Not sure what you're after here. There is a large (the main) ground point on the other end of the heavy black lead heading away from the battery negative, it should be on the engine block.
Then there will be numerous others. In the YD25 D40, the ECU had a ground point right near it, but nothing else that we've had many issues with apart from the instrument cluster inside which sometimes earths through the stereo (or vice versa) causing random havoc with the instrumentation (fixed by adding an earth wire from the stereo body to a dash mounting bolt).
