If you have a big one to penetrate with or just don't want people seeing the wires every time they open the door, if you're running a sport cage. There is a hole right behind the battery box on the passenger side. Attachment 598643
Outstanding. I have the cage sitting on the floor about to be installed so I did not want to use the penetration next to the door.

Below that behind the wheel well is also an opening where the factory wiring harness runs. You could go right through that grommet and get the wires from under the dash on the passenger side.
