There IS an UNUSED, female ended, Brown wire inside the headlight shell on US versions.....It's common with the taillight brown wire and is part of the "park" circuit....
There should be FOUR Black/white stripe wires.... two of which are the coil positive sides, and the third is the double female connector ended one (into which they plug) which goes forward in the harness to the headlight shell, then connects to #4, which goes to the right side handlebar switchbox, and is powered when the "KILL" switch and key switch are on.....#4 may be solid black with just a white "tag" of shrink tubing near the plug......
