Hey guys....planning on looking at a friends headlight wiring from his 09 Fatbob.

Does anyone have a wiring diagram I could take a look at?

Thanks in advance.

 Here you go.  Unless someone has an electronic copy, you are stuck with this.  There is about 10 pages to make up the full diagram.  If you want both headlights on at once, there is a lot of info on this site.  I just got a DOMESTIC light from the states (back in the good old days) and it plugs straight in.  Piece of piss, 1 bolt and 1 plug
