Jon, if you look up under the dash to the right of the steering column, you will see a black grommet with nothing in it. You can pop the hole right in that grommet. It's big enough for 0 guage wire by the way, so you should have NO problems

 

thanks alot guys i almost took the drill to the firewall!!!
