Just installed the Yoshimura FE kit and it is a top quality item, it utilizes the factory signals and looks like it came with the bike, only wiring that required is to mount there trick looking license plate light, all and all a great install
Not hard at all! Yes you will remove the factory turn signals from the factory fender unit, attach them to the bracket. The factory turn signals mean you dont have to splice in a new connector for the turn signals. The only splicing you have to do is on the led license plate light. Don't be afraid! A simple snip on the factory wire, use a stripper and strip about a centimeter off to expose the wiring on the inside slide it into the connecter they give you and crimp it down tight around the wire than do the same on the yoshi led light wire. Route it back through the hole underneath the rear seat and your pretty much good to go. Makes the bike look 10x better.
