Expert Reply:

On your brake controller the red wire is the stoplight switch circuit of the brake controller and it would wire to the green wire of your harness that is labeled stop lamp.

The black wire of the brake controller is the 12 volt power source and would get run to the red wire of your harness that is labeled feed wire.

The illumination circuit isn't used.

The blue wire is the brake output circuit of the controller and would get run to the blue wire of the harness that is labeled electric brakes.

If you just want to run the lighting functions on the trailer, you can just use an adapter like Adapter 4 Pole to 7 Pole and 4 Pole, #37185. Plug in your 4-Way flat to the back and tape up the rest of the wires with the exception of the white ground…
