Actually it just occurred to me that you probably wouldn't be removing the OE turn signals, which is generally a big goal of 5th Gen'ers (De-Dumboing).
So you wouldn't have the OE socket to use. But there's always eBay!
In the break glass and reassemble method, you only have the housing to reuse. Wires stay in the GSXR stalk, unused. I bought a three pack of red, black, and green wire and rewired the whole thing with bullet connectors to fit through the new hole in the upper fairing.
Then of course, filled and repainted (Or paid someone to do so) the turn signal holes.
I'm guessing you would want to use the "trailer conversion" thingy to convert three wire from the bike to 2 wire to the signal. Or not bother with running lights since you are keeping OE signals? On the 6th Gen, the turn signal holes would make a nice "ram air intake'!
