Remove the left inner tray under the handlebars and the phillips screw at bottom near the wheel hub.
Reach behind the speedo to get the cable unscrewed from the housing, here is where the cussing comes in, small hands help, then tie a string to it.
From the bottom lift the cable out of the fender guide and then the whole cable comes down and out the bottom.
Use the string to pull and guide the new cable up from the bottom. Make sure you get the lower end back through the fender guide.
10 minutes tops. Cussing factor of 3.
