There is a company here in Texas that has the Yaffe's in a package deal with the wires already ran, but it is like $1,400 I think. On the website click on the "Handlebar Kits" they don't show the picture of the Yaffee package, but they sell his bars so just call them and they can give you a quote. The list of the brand bars they sell is under the tab Handlebars.

Good Luck
I originally bought a set of the 12" Yafee bars from them. When I got them they were scratched and circle with a black marker. When I called them they told me it would take something like 12 weeks to get another set.
I called Yafee and the set me a set the next day just on my word and asked that I send the scratched ones to them. They were a little embarrassed.
Hill country was no help but got the sale. Just my experience.
