200 series aux wire route

[kng]

I am trying to find a place to run a 10 gauge wire from the battery to the left rear for aux switch panel. Does anyone
know the best way and where to get through the firewall?
Thanks

There is a fairly large pass thru boot/grommet that is a great place. One exists on both driver and passenger sides. Then route down in the door sills, you'll see the way.

BTW while you're running the wire back it is very easy to extend it across the rear to have power on both sides back there
