In this picture you can also see the "forest of tabs" ground block. I will connect a ground wire to the back where the batteries are, and two ground wires to the engine. The engine ground is critical. If I lose that, I'll fall out of the sky.
Here are a couple of quick photos of the contactor for the alternator and starter. I really don't need a starter contactor, but to simplify wiring, I've connected the alternator to the starter, and the starter to the contactor. There is a diagram here: http://www.rv8.ch/article.php?story=20041121101637759
