If you crawl under the driver's side of your dashboard, and look by the gas pedal drive-by-wire assembly box (where the throttle cable assembly would have been), look just to the left of it. You will find a rubber gromet and a pre-drilled hole in the firewall. Push the gromet out into the engine bay (it should fall right to the ground as there is nothing directly under it) and you can run your power wire through there. I took the gromet and cut a hole large enough for 4 gauge to fit, and reused it when I ran my wire. Then I used some silicone sealant to make a nice tight seal.
From the engine bay, you will find it if you look to the left of the brake master cylinder.
