No wires to cut just plug and play for most people. I am going on a long trip in the to shenandoah mountains and don't want my phone to die on me in case of an emergency. So I saw this at wal-mart for $3.00. I already have my bike wired for a battery tender and the plugs are the same. so if you use a battery tender you are all set. this mod would work even better for bikes with the battery under the seat. Put you phone under the rear seat to charge.
