The two blue wires are not yet connected...the lights are though.
Using a connector for the trailer, that has flat blades, is not a very good idea.
One grain of sand, will stop a good connection.
Also, in time, it will corrode, especially on high current terminals such as the brakes, charge line and ground.
Then, it must be cleaned and cleaned and cleaned again and again.
Using the round terminal type connector, never has the same issues, since the terminals are called "aircraft type".
It self cleans every time you connect or disconnect it.
Costs a little more, but beyond comparison, because of it's superiority.
