Running light issue
 

Hey, hopefully someone can help me out. I had lost my running lights on my 2013 gmc sierra 1500 and I had found the wire that's causing the problem, it's a orange wire that's disconnected from somewhere? Had no wire exposed or connection on it, looked like it was cut, I put a power on it and the lights work properly again,(auto feature will turn them on as off) I'm assuming it's suppose to go to the BCM but I have no clue where. So I guess what I'm asking is does anyone have any ideal where the orange wire for the DRL's plugs into or a wiring diagram.
Thanks for any advice given https://cimg7.ibsrv.net/gimg/chevrol...edd56cd53b.jpg

How did the wire get cut? Was someone doing some work on it? Where is the wire, under dash or under the hood? Anyway if it was cut there should be another end of an orange wire in the vicinity that it should be connected to. Stretch out the wire in all directions and see what it could reach to and hopefully you will find the other end of the orange wire.
