Hello all

I am getting to the end of my re-hab project on y '76 Yarcraft Yankee. I've re-installed the outboard (the one referenced in the subject) and controls. I'm trying to re-connect all the cables from the control to the motor. The big round plug is obvious. Apart from the round plug from the controls to the motor, there is also a thick (maybe 6 ga) red wire which I assume is power from the battery, and a less thick ( maybe 8 ga) black wire, which I assume is ground. There is also a much smaller (perhaps 16 or 18 ga) black wire. I see it on the wiring diagram in the manual, and its listed as the "Powerhead Ground" (along with the thicker black wire) I was hoping that someone who had the same motor could perhaps post a picture of the starboard side of the motor where all this wiring is so I can verify that I attached everything to the right place. The service manual includes no such image, and the wiring diagram isn't being much help other than to identify the wires, not where they connect though. Thank you all in advance for your help
