Sometimes the functions of the wires are listed on the light housing where the wires come out of the light.

It is likely that green/brown is running lights for the right side, green is right turn signal and brake lights, yellow/brown is running lights for the left side, and yellow is left turn signal and brake lights.

Once you have determined the functions of the wires you can connect the new parts. The new plug should have the following functions: white is ground, brown is running lights, yellow is left turn/brake lights, and green is right turn/brake lights.
