Mystery red wire with a fuse in it
The third pic, at the top is where the red wire is connected to a half black half white wire, the two wired are just twisted together and wraped in electical tape, i took the old tape off cleaned it up and reconneced and taped the wires together.
The first pic you posted is exactly what you have circled in red, it must be a glare that makes it look like wire
is the other end connected to the same b/w wire??? that's a pretty big wire to be in there as it is...seen wire like that for car audio...I'll have to look at my bike in the morning when I get home...
Ill send you a pic of where the other end goes
