Need some help trying to wire this LED headlight to my 00' BUSA. I am not sure where the last back wire is suppose to go. I tried contacting Sportsbike Lites but have not heard back from them yet.
If that (the black) wire is the only one not connected the I would tape it off and try the light.
If it works then maybe you don't need it. If it doesn't work then I would hook the black wire to a ground and try it again.
I assume that there is a fuse to protect. So hopefully the worst that would happen is you would blow a fuse.
Good luck and let us see the final outcome and how it looks on the bike.
