I'm working on mine right now, we'll see how it goes.
To you guys removing air boxes and battery trays and headlights -- you guys do know all you have to do is reach under the driver's side bumper, in front of the wheel, and it's right there, right?
You don't even have to pop the hood (other than to disconnect the cable from the DSI lever and snake it out). All you've got to do is reach under the bumper, remove the bolts, uplug the wire, and pull it out.
You can do it by feel if you don't want to lay on your back or jack it up.
