well its got a wiring harness which is good. However id you plan on using the bulbs in your stock assembly, please DONT. The bulbs he is selling are probably D2S, which are for projectors. You need the right bulbs for the stock reflector, you need D2R bulbs. I have the origional Hella ballsts with Phillips 4100K D2r bulbs, looks like a factory installed HID. Everyone loves it around here
