A little help with Lexus DRL diagram

I picked up a set of 2015/2016 Lexus DRLs off a Nx200. It has 4 wires, black, yellow, white and green. I assume the black is ground and yellow is turn with one of the other 2 either being a constant power and the white LEDs or the other 2 being a bright and dim mode when the headlights turn on the for the white LEDs. Regardless, before i start touching wires together on these does anyone have a diagram or can lead me in the right direction? I rather be safe than sorry.
