I agree with Joe. I put heritage style black bars on my 09 and you need to take the fairing off to disconnect the TBW connection so you can slide old wiring out enough to get to the famous green connection. It took me 4 hours to change bars, but not very hard. Take your time and follow the manual or other members posts.
BTW, th eheritage bars are awesome. One of the first things I should have done. Enought rise and pull back. Enought slack in all of the TBW connection, clutch and front brake cables, so no need to change them.
I do think HD has a TBW extention they sell now for higher rise bars, but then you may need new clutch cable and front brake lines, but not 100% sure.
Good luck.
