Never found a useable entry hole on our 2011but you may be able to do what we did.Go under the car at the transmission hump.Underneath the car, about 12 inches from the back of the hump on the drivers side ,and about 4 to 6 inchesin from drivers side edge of the hump , there is a double wall floor. You will see a 3/8 inch square hole in the bottom floor. Drill a pilot hole thru the upper floor and you will find you will be under the center console at a place that is easy to access for wiring. After drilling out larger for the wire, paint the exposed metal, then rubber tape and silicone made a good seal. Hope this helps you.
