need help wiring my 4 wire utility trailer plug on my towing package

2003 toyota tacoma dc 4x4,long story short I got a new towing package and need to know what color wires from the connector that runs the lights for a utility trailer go to what color wires on the truck. Its a 4 wire connector (yellow, brown, white, and green) just need to know what color wires these need to connect to on my truck wiring to make the trailer lights work. thanks

on the connector:

green- right turn/ stop
yellow- left turn/stop
brown- tail
white- ground

 

I've had 2 of those splice in convertor boxes go out on me, they kinda suck. I'd return it and go with the factory harness style one
