I actually did both, but found it was easier to get to above the wheel.

The yellow wire in the photo certainly is the 12 volt supply to the headlights. It appears that the black is ground, as has been mentioned in YouTube videos. I have not yet found which wire controls the parking lights.

I just used the putco harness and modified it pretty simple to do.

Those eventually fail and when they do will cause a short. Also the time I saved trying to figure out which wire does what made it worth it for me.
Understood.

But you still have to modify the harness and add wire, so it doesn't save that much time.

With the modified harness does the emblem only come with the lightbar and headlights at dark or is it on all the time the truck is on?
