I assume you mean the part that converts the turn signals to brake lights, so that you now have 3 brake lites vs 1? I use a similar switch from kuryaken(sp) which does that but also converts the turn signals into running lights (i.e. 3 rear lites at all times). They also serve as add'l brakes lights.
I agree, hard to figure why this isn't stock (although I suspecy i can guess).
