These new lights are not always color coded. The dark green wire will be the stop/turn light & connect to the green wire in the harness when used on the right hand side. It will connect to the yellow wire in the harness on the left side. The black wire will go to the brown wires on the harness on both sides. The ground is provided by the mounting brackets. You can verify this by touching each wire to a terminal on the battery & holding the fixture against the other term.
