Your wiring harness is what is called a wishbone harness. The white wire is the ground and is attached to the only covered pin out of the 4 on a trailer side 4-Way.
The 2 brown wires are running lights; one for each side of the trailer.
The yellow wire is left turn signal and brake lights.
The blue wire, which is normally green, is the right turn signal and brake light wire.
