The easiest thing to do is to drill a hole between the brake and gas pedals. feed te wire through and put a grommet through so the wire doesn't chafe. If you are worried about the warranty, stop. as long as the install looks professional (wires are all tucked away nicely and there isn't 30lbs of liquid electrical tape all over the place), the dealership will assume it was professionally done. If you are worried about hitting something on the other side, that area is pretty empty. I'm running 4G wire and my hole didn't interfere with anything.
