VLED V6 Switchbacks

I currently am running the V3 Triton Switchbacks on my 2015 Tacoma and I opted not to tap into the headlight wiring during the install so the DRL's dim when the headlights are on. I am upgrading to the V6 Tritons and just received my order yesterday. I want the DRL's to dim when the headlights are on this time but not sure which color wire I tap into on the headlights per the instructions. I have attached the part of the instruction indicating what needs to be done. Can someone point out which wire it is?

Thanks in advance

 

Anyone
