Having problems with my brake lights. Let me explain, headlights, tailights, flashers, signals all work with no problem. One brake light works (but only with signal lights on, turn off signal lights, apply brake and no brake lights at all. Any help you could give me on this issue would be greatly appreciated, hope to hook up my horn in the morning as well, if I can only fix these last two issues, then I can cruise my new purchase, thanks HUGH.
