That's where I have mine now, but the excess cable, along with the excess antenna cable, pretty much fill up the fairing pocket.
Also ties up the power plug keeping me from charging the cell phones when I need to (I make several Chicago - Abilene, TX trips each year and use my J&M cell interface).
Winter projects include routing the power cable under the top shelf and into my power strip installed under the seat. And finding a shorter coax for the antenna. And figuring out where to better mount the control head.
