I just bought dual halo projectors for my accord, and i was wondering if someone would help me out. I know where to wire the halo's, i know where to plug in the high beams and projectors, but there is a third light that has a wierd plug on it, and i dont know where to hook it up. If someone knows what i'm talking about or if you know a website with instructions, you would be helping me out alot. Thanks. It is the outside light (not the turn signal)
