I sent a power line through on the passenger side through a big rubber grommet.
^^^From under the hood.
^^^From inside passenger footwell.
I don't know how much the 08's have changed from my 06, but I also ran some wires through an unused grommet just behind the brake master cylinder on the driver's side of the firewall. There are a few other places, like through the hood hinge opening, as well.
