Cable through bulkhead (firewall)

[Minesthechevy]

Hi all. I'd like to pass a couple of electrical wires through the bulkhead - I assume there is a hole somewhere already that does just that, with a grommet. Where should I start looking, and is it an easy job? TIA

Look for where the main harness goes through the firewall from engine bay into the cab.
I used a knitting needle to fish it through.
Use something with a smooth point so you don't damage any wires.
