At this point, I think you have nothing to lose. I wish I had experience with your more recent model but the handle bar can be removed for sure (I am still a bit surprised that you are having this issue on a 2014 model though). Don't go crazy about cutting wires but make very sure that your job is waterproof, use some shrinks and even better if you can lead solder the wires (I didn't). You will not harm anything (keys, computer, etc.). Make sure you do the job out of water or make very certain that you can't lose some of these tiny washers.
Good luck (I too didn't have any experience when I did my 2003). From this point on, you are on your own.
