Yes, I just picked this kit up off amazon. 69 for everything. GKA tries to play it up like it's plug-and-play with no real effort, but as a noob, it definitely took me a while (Thank god for whoever the dude was that posted up the Targa FE installation process - my savior) **NOTE: You will HAVE to have a new flash relay for these blinkers to work. After I had taken the entire back end apart, cut the license plate light wires and spliced them to the new ones in the kit, and ran the signal wires I realized the signals were steady-on as I tested them. I contacted the company and their reply was that they "sometimes sell the kit that includes a new relay" - no idea what the hell that's supposed to mean as they claim that it's customized for the 300. They said they'd be willing to send me the relay after the fact. I didn't want to wait two weeks with my bike in pieces in the garage so I ran to autozone and picked up the Tridon EL12 for 12 bucks. If you do get the EL12, it's straight up plug-and-play. However, I'm fairly certain that this relay only supports one set of LED signals. Meaning, if I ever decide to switch the front end out with LEDs also, the EL12 will have to be replaced with another relay.
So yeah, if you like the look of it like I did, get it. Just know that a relay is mandatory.
