I retained the handle bar electrical controls for the most part. Bright, dim, signal, horn, engine stop will all be retained. I had to ring it everything and then change out the connectors to something that is readily available. I went with the Delphi weather pak stuff since i had some around. Done of the signals were not needed and were isolated and tied back. I also retained the key switch and lobotomized it as well and changed to friendly connectors. See pics.
