Not if you are accustomed to doing such work. Splices in the auto and motorcycle world are often done substandard...but if you will solder and shrink wrap the new joints they should be secure....obviously you'd use the same gauge wire to splice in.
I have done mine to fit the ape's and have no drama just watch the color of each and should be Lloyd good. Use solder and heat shrink on each wire not plugs as they are to bulky.
