Yeah, the thing that took me longest was taking the grill off. So dumb!
The only thing that's not plug and play is the red tab/wire for the LEDs/halos/Eyebrow. You have to bend the metal from one side of the tab to the other. AND it's polarized, so if one direction doesn't work, you have to flip it. Hopefully that makes sense. At first I thought mine were broken, but then I realized I had to flip it.
Edit: I would also note that you will be using your stock bulb socket from your side markers. The red tab plugs into it as if it was the bulb. And in case you need a link, here's the thread for the install: 2008-2011 Halo-Projector Install Guide
Edit edit: And if you've never removed your headlights before, be careful when removing/replacing. That metal spring clamp on the bottom of each headlight assembly WILL scratch your bumper if it touches it.
