I use 1/0 its fairly easy to run. pull the door sill panel out then there is a small plastic piece under the triangle window then pull the plastic piece that goes across behind the seats. be very careful not to break these pieces. now pull the carpet on the passenger side up run the wire through the grommet that you know run it under the computer under the foam run it to the side of the seat up the wall to below the window there is a perfect spot to run over the wall you will see this spot when you take the panel out that goes behind the seats. let me know if you have any more questions.
