Where do I run a power wire through a firewall In a 2009 Pontiac G6?

To run a power wire through the firewall of a 2009 Pontiac G6, locate the rubber grommet on the driver's side near the brake pedal. Carefully pierce a small hole in the grommet or use an existing opening to avoid damaging it. Once you have access, feed your power wire through, ensuring it's protected from sharp edges and secured away from moving parts or heat sources. Always double-check for any potential interference with vehicle components before finalizing the installation.
