Just got my 2009 Kingpin and didn't even realize before I brought it for inspection that there was no plate holder. Installed that last night, but the wiring is a mystery to me. There are three wires coming into the rear fender (white w black, red and violet). The tail light also has 3 wires, and of course the new plate holder has 2. Anyone have a wiring diagram or advice on how to wire this properly? I'd love to do this myself and avoid bringing it in for service. Thanks in advance for any help you can provide.
