If its the wiring you are working on, it is best to remove the fender. All you have is 4 bolts on the struts the fender is off. Removing the rear wheel will take removing the adjusting set screw plug, backing off the adjusting screws, removing brake caliper, rear axle, belt or chain, them comes the fun part putting it all back together and aliening the rear wheel.
If it was me I would remove the two rear strut bolts and just loosen the two front strut bolts, raise the fender up and you can get your big hands and more in there.
