Typically, the yellow wire carries the left turn/left side brake lamp circuit. The green wire carries the right turn/right side brake lamp circuit, the brown wire carries the running lamp circuit, the black wire carries 12-volt power from the battery and the white wire is ground. You can confirm this by connecting the white wire to the negative post of a car battery and applying power to each other circuit to see which lamps light. We recommend confirming because the color codes aren't always followed.

I'll link you to an article about trailer wiring that I hope you'll find helpful.
