You got the main engine ground correct.
Also the other ground you are thinking of goes from the head to the firewall(stock is a small braided cord to a clip on the firewall).
dont worry about the plug with the clear plastic around it, you dont need to mess with it and ive never seen it connect to anything(maybe a diagnostic port).
