I ran a 10 ga wire back to the spare tire well. I used this side because it was easy to fish a wire thru the grommet that is in the firewall. also the stock wiring goes to this compartment first, so it was easy to figure everything out.

I used 10 ga so I can also have a 12v outlet back there heavy enough to run an inverter, 12v trouble light,etc. from, even while backing up! or if needed, you can jump the relay and use the lights for other uses while parked.(fishing, tailgating, camping, etc)
