When I was looking to purchase mine (HID's) I called 3Bspec to inquire about their HID kits and the relay harness. I was then informed about all the misinformation on the internet and didn't require a relay harness for a 35W setup. In his opinion our cars are more than capable of handling the requirements of the 35w HID.

I made my own harness without a relay for my projectors. (9007 socket split into a 9005/9006) and haven't had any problems in the few months I've had them installed.
