I had a set of Khromewerks sweeper +2 bars #300505 on my 06 FLHT , I really liked them.
I'm considering the same bars for TBW # 300515 for my 09 FLHTCU.
Supposedly it would require a # 38649-08 clutch cable for the new bike.
No internal wiring needed or required for these bars.
Do a search by a member called BertK he did a great pictoral on this bar swap.
Here's some pictures of the swap

I will do this swap this winter on mine.
