Wiring help

Please help! I'm trying to install my first remote start system into my 1999 Avalon and it has a safety hood switch. I need to thread a wire through the firewall into the engine compartment so I can hook the hood switch up.



I found the big grommet opening that I can get to but it's on the passenger side. Now, I can't figure out how to easily get the wire from the driver's side to the passenger side so I can make use of this big opening in the firewall.



Or is there another opening on the driver's side that I'm missing?



Any help would be appreciated!



Thanks a ton.
