The banker has it dead on. You have to use 3/8" bolts for the battery tray and 3/8" j bolts for the hold downs to meet NHRA. I did it very similar except that after the Master Switch, I ran it behind the finish panel and then around the drivers wheel tub and down below the x-brace, under the rear seat and into the channel. I replaced the grommet hole he speaks of with a 2004 Jeep Wranger Grommet which has a double seal and is the exact same oval size.
