2017 sierra wiring question

Recommended Posts

Just installed some small LED accent lights in the small scoop above the grill.  I planned to connect at the headlight harness below the left headlight.  There are eight wires on the harness.  I'm guessing it's best to hook into the driving/parking lights but  which wire is it??  Some youtube info said yellow but ....wrong.  I don't have a manual and can't find a 2017 diagram online.  Alternate connection points are welcome.    Any info is appreciated !

I don’t have an answer, but I’d like to see the set up! Post some pics please!
