Good Firewall Where Is A Good Place To Run Wires For A Switch Through The Firewall?

Where is a good place to run wires for a switch through the firewall? - good firewall

I have a 98 Ford Taurus sedan, and I wondered if it was a good place to get a cable through the firewall to install the battery, so you can click on a switch, some leading lights in conjunction with my car. Your help would be very grateful. Thank you.
