It was extremely easy to install. i didnt use a battery or relay or anything. just plugged the stock headlight plug into the supplied harness and done. the hardest part was finding the right spot to put the ballasts in the air plenum.
I will get some pics tonight of the setup
Here are some pics of the install. The kit comes with metal brackets for the ballasts to mount on but i chose to silicone them to the air plenum instead. Other than that it is just a plug n play kit. I have the 8000K bulbs
