Inverter Install 2005 Yukon XL Firewall

[dinojr]

I am trying to run the cable for a 1000 watt inverter that I am installing under the drivers seat but I dont know where to run the cable through the firewall. Is there an existing hole I can go through. I am using quality cable with excellent shielding on it. If you can include photos I would appreciate it. I am a novice. Thanks in advance. Brian

Under the hood to the right and belowthe steering column is a huge grommet. I used it to run my amp power cable.
