I cut my header panel using Stephen/Bama's pics and everything went fine. You can get by with just the pigtails that are $39.99 I think, but you can also get the upgraded harness that uses a relay, I think it was like $89.99. The other option is the brightbox relay. It will have your low beams on with your high beams. There is a way of doing this with a diode on the relay harness,but i'm not sure how. I used the pigtails because I waited for a month for everybody to get the relay harness' in and finally gave up on it and went with the pigtails. Bill's a good guy and he'll get you fixed up.
