I haven't done it myself, but how hard is it to pull the rear half of the rear fender, and just unplug/rep lug the wire into the connector?
Easy, remove the two rear bolts on the side of the fender and the smaller one on top near the seam of the two parts of the fender. Support the fender when removing the final bolt, then drop it down and you'll see the connector up under the forward half.
