The Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Socket - Metal - Vehicle End # PK11404 will have the wires labeled in the following manner:
White - Ground
Green - Right Turn and Brake Lights
Yellow/Red - Left Turn and Brake Lights
Brown - Tail Lights

I've attached a video to help with this pin out.

If you are looking at the 4 pins. The bottom left is ground, the bottom right is running/tail lights, the top left is left turn and brakes and the top right is right turn and brakes. I've attached a photo to help.
