there is no current DIY writeup, but the install is pretty straightforward.
The plastic trim on the bottom comes of with about 10-12 10mm bolts....
Assuming you gut a simple plug-and-play module with the ballasts, all you need to do it unplug your foglights, plug that to the ballast, plug the pallast to the HID bulb, then put the HID bulb where the other bulb was. then you need to safely mount the ballast so it doesnt fly around, and you are all set.
If you didn't go the plug-and-play route, you may need to do some cutting and soldering where you would otherwise just unplug the oem foglight and plug that into the ballast.....if you post the brand or what you have it would be easier to help...
