    Nearly any of the rubber grommets in the firewall have openings that are usable. You'll want to cut a hole in them to route the wire through.

    I think the closest to the battery would be the one used for the oem boost gauge (just behind the intercooler).

    I believe that'd be the easiest as well

    that one was pretty easy to because it was close to the battery and the side that i wanted to run the wire on

    firewall holes

    will these firewall holes allow a 4 gauge wire to pass thru? and has anyone found any other firewall holes besides the one behind the intercooler? thanks!

    I used the one behind the pedals. Two four gauge wires and a vacuum line for boost.. although I was never able to get the grommet back in properly.
