Wiring Through Firewall - Need Help
 

I need to run a few small wires through the firewall. I have done a search and heard that many go through a grommet behind the battery on passenger side. I am trying to go through the driver side instead. Is there any grommet that I can go through? I was told that there was one by the brake fluid res. but I am having a hard time locating anything. Please help...
