from what ive seen there isnt a kit, people but H4 headlight conversions lights from painless for example. Then you can either make your own relay harness to avoid running all the extra power through the headlight switch or buy the four headlight system harness from hella. Lastly you purchase a HID ballast and bulbs from about anyone online they are all over ebay its how most people convert there current h4 style headlight vehicles to HIDs and then your done.

inboard lights
Painless 4 headlight system relay harness
Headlight conversion harness
Then all you need is an h4 to HID conversion ballast and bulbs off ebay and your done.
