If I recall correctly, that wire is routed up to an unused harness pigtail under the seat, and it will fit only one of matching shape. It is a pain to route correctly. I hope others will agree with my recollection or correct it. Good luck.One way (upshifting) is exactly what I want the bike needs help shifting perfectly on its ups. Sorry if my orginial comment was to vague. What I'm confused on is there going to be a capped off pigtail where I can add this quickshift or do i have to unplug something and override?
