On the 5 pole trailer connector provided by the # C56515 T-Connector, the color code/functions are as follows:

White Wire Feeds Pin- Ground Connection
Brown Wire Feeds Adjacent Socket-Running Lamps
Yellow Wire Feeds Next Socket-Left Turn/Brake Lamps
Green Wire Feeds Next Socket-Right Turn/Brake Lamps
Blue Wire Feeds Final Socket-Feed From Reverse Lamp Circuit

I've provided a photo showing this, and I'll also link you to a help article that contains all kinds of information about trailer wiring.
