1. If you're using the stock turn signals, have a friend around to help you jam the old signals into the new fixture. The rubber is almost impossible to squeeze in by yourself. Get one side in and then have a buddy try to poke the other end in with something like a small screwdriver.
2. The wire casing for the new license plate illuminator. So R&G provides a few wire protection hoses for your license plate illuminator(the 2 additional I assume are for if you order their tiny led turn signals) and this is probably the worst thing to do on this mod. You have to pull both prongs through this tiny tube. I would recommend fashioning some make shift device using a wired hanger or something. I had nothing as I was doing it in a friend's garage and it mustve taken me 40 minutes just to get the 2nd prong through. Awful.
