Got the hitch wiring done tonight. Used the TowReady T-one harness from etrailer. Easy install per the directions, but I made two changes. As mentioned earlier, there is the power wire under the rubber grommet on the driver's side. I used a tap splice to connect the power from there to the harness. Much easier than running a wire up to the battery, and still kept the gray factory connector intact in case it is ever needed in the future.
Also, the directions call for running a green wire under the vehicle from the left side to the right side tail light compartments. I was not excited about having that wire under the car, so I ran a stiff fish wire from just inside the tailgate opening in the cargo area outward toward the left tail light area. It pokes through into the tail light compartment. Then I cut the green wire that is connected to the harness on the left (driver) side, taped it to the fish wire, and pulled it through to the cargo area. Same procedure on the passenger side, then just used a heat shrink butt splice to reconnect the two ends of the green wire, and tucked it under the trim. A convoluted description, but I think a much more pleasing result.
