Ran a 4 gauge cable through there very easily. I taped a feederwire to the cable to fish it through first.

Chaz, as the guys say, there's a grommet through the firewall behind the battery bay. I routed wires next to the main harness through the grommet. I used a small piece of wire to poke the wires through into the passengers foot well.

Thank you all! DeeGee's pic really helped along with the rest of your advice, and my underbumper lights work. (even better after I realized I had the switch upside down)
