I can't determine where the ground wire is bolted to. I suspect it goes to the frame because the box is on rubber isolators, but then again, the lights normally ground to the box, ... So there would have to be a ground strap somewhere.
The fastest for now is to determine which you're missing, 12 volts, ground, or both. Use an ohm meter to measure the resistance to the frame on that ground wire. It should be real low, as in a couple of ohms. If you have that, test for 12 volts on the dark green / black wire. A lot of digital meters don't respond fast enough to catch that during the first second so a test light might be more accurate.
