Normally on electrical connections the bronze/gold screw is meant to be your hot wire. The silver is neutral, and the green is ground.
On this particular connector the only thing that really matters is that proper wire corresponds to wire on other side of the connector. There’s no ground or neutral reference on the connector, so as long as wires line up properly it will work. And despite colors, if you look close each side should have a number or letter to make sure you get wires terminated correctly.
I did notice your individual wires look a little long. If you trim them back a little the screw on nuts will clamp down on outer insulation. That’s what makes it waterproof, and will help wires from getting pulled out.
