2008 Jeep Wrangler Firewall Grommet

[TheJazzMan]

I've installed the towing baseplate, CoolTech harness and now I'm installing the Air Force One auxillary braking system. I'm to a point in the wiring where I need to run a wire and air hose through the firewall, but I can't seem to find the best place to go through. I see what I believe to be a very large grommet on the passenger side of the firewall that leads to a point under the battery tray. Is this the right place to go through or is there a better one?

After contorting and straining to see a way to get through the firewall, I finally gave up and searched the Jeep Wrangler forum where I found the solution. To the left of the brake pedal is a 1.5" hole covered by a thin rubber membrane. Just poke a hole in it with a fishtape or coathanger and pull your wire through. ON the engine side, the hole is to the right of the brake booster cylinder.
