There's already a hole. Just follow the pack of wires to the firewall. There's a large grommet that they go through, but there's plenty of room to run any size cable through!
There's a little nipple on it, too. If you snip the end of the nipple off with some wire cutters, a 8gauge wire should feed through quite nicely.
It took a some trimming to get my 1/0 wire through.
