Aloha Larry,
I have the same motor in my TR3A. The green wire (fused power supply) goes to terminal #2, the top motor terminal. In my car a black with green tracer goes to terminal #1. There are probably terminal numbers on the motor end casting. The black ground wire connects to the motor housing bolt as you have it. The other black wire is an additional ground wire to the body. So as I see it, going top to bottom, Black, Green and Black with green (currently unattached wires.
Safety Fast,
Dave
