Me too. If you look at the trunk floor on the passenger side, you will see a rubber plug there in the perfect spot if you mount the battery box behind the wheelwell on that side. Use a grommet, run it through the subframe, thread it around the rear suspension and gas tank (make sure nothing moving is near it) run it along the fuel line, above the heat sheilds to the driver side of the engine compartment. then fish it up the firewall, behind the shock tower and to the connection. Thats how I wired mine 1.5 years ago and haven't had any problems.
