I'm concidering buying the cvo minister fender to match my viper bags. I spoke with topshop and after talking about the cvo lights they offer at $395 and another $125 for the harness I couldn't help but wonder why so much? Through boarder tracker I can buy both lights the factory cvo harness and the 6 factory screws for $332.54. If purchased through topshop I'm into the lighting for $520? I realize that topshop makes there own harness but is there any reason not to use the factory cvo harness?
