Xplosion, its REALLY REALLY REALLY easy to install these, don't bother paying anyone to do it, if you need help PM me and i'll give you instructions and you still can't figure it out, i'll call you to talk you through it. Step 1. unplug old bulb. Step 2. Plug the new power connectors into the car's power plug ( the one that you just pulled the bulb out of) Step 3. secure the HID bulb in. Step 4. Move the ballast to a secure spot. Step 5. Your're done! I"m running a set of ebay ones from china, i've run them for almost 1.5 years now. absolutely no problems, and i've transferred them from my corolla to my new car now (both are H7) If you had to buy either of those 2 kits, get the 2nd one.
