There are plenty of videos and discussions that solve the problem of the missing blue connector in the headlight bucket on the USA wiring harness. They show how to hook up a USB charging port but the same technique would show you what to do for the grip heaters. I think, however, that Jensen is looking for the same thing as I am. A "Y" connector professionally manufactured that has a male and female brown connectors for passthrough for the brown connectors in the headlight bucket and the blue connector off to the the side for connection to the grip heaters, USB chargers, and so on. So far, I have been unable to find one, and I don't understand why Kitaco or Takegawa or anyone hasn't made a production one, as we have had the problem for three years now. If anyone has found one, please post a link.
