I'm sorry, I was thinking of the high beam I did. It's just plug and play, link on page 3 for high beam.
I don't think you have to actually modify your headlight. Looks like you just need to devise a way to hold the bulb since it's a H7, look at Shify's pictures.
I'm doing a low beam retrofit on mine soon and going to try something different for my high beam. Instead of 3000K yellow, going to get a new bulb that has a clear lense around it, like 04LE's, and put some orange/amber colored vinyl on it in hopes it'll give out a nice bright orange for some thing different.
