Dude I bought the same ones from the same guy and it takes him FOREVER to ship them, dont expect them in any less than 3 weeks, I even emailed him and asked and he said he had to make up a few sets. All the while he knew I needed them. I had emailed him for weeks prior telling him that I wanted a set and he allegedly emailed me when he had them ready. Anyway, they go together nicely and are pretty easy to do. I recommend taking the bottom shield off the undercarriage and taking the wires with the T-taps he'll send and just slice the wires in, cause the T-taps SUCK! I have issues with it all the time and I also note that the lights don't always turn on, you have to switch it on and off, especially if you leave it in auto mode. Good luck, they are nice lights overall for a good price and I did the same thing, I ebayed the working bulb and made almost $200.
Edit: Oh btw- he won't leave you feedback first, although you paid right away, so I recommend not leaving him any cause he uses feedback to retaliate. I hate ebayers like that. I pay first I get feedback first.
