I posted a how to with pics, it's currently installed as in photos on my bike.
It's 1 fitting and 1 line.
You remove the line that runs from the MC to the splitter under the tank. The install the adaptor on the splitter, and install the new braided line from adaptor to MC.
All told about 1 hours work and $30. The lines are already braided steel internally, so, there's zero performance gain with the full replacement kits, but they do look great!!
