I ran my 1/0 on the driver side door sill. There was a grommet for the gas pedal wires that i sliced a bit larger to fit the cable. Then removed the rear seats and ran it attatched to the back of the hump ( behind rear seats). It was a little bit of a pain in the ass just at that point, trying to make sure the cable doesnt get schaffed on the seat brackets. I also ran the ground the same way behind the driver side rear cargo panel, and drilled a whole in the rear tool storage compartment, and grounded to the frame. This was my first install in any car, and i personally diddnt think it was all that hard to run the cable. What kind of cable are you running?
