What switchgear are you talking about? The H4/H11 harness adapter?
Sorry missed your post.
By left switch gear I mean the left handlebar turn signal + headlight switch. I don't know about other naked bikes but the in the 9er the headlight connector is tied with this. So in my case I already have the H9 connectors for the 599 headlight wired so there is no need to do anything with my setup.
