Cannot find a place to run wire through firewall (2011 tahoe)

[hillstrubl]

I found a factory grommet that I could use, just next to the brake booster, but I can't for the life of me "find" it on the inside. I am shining light through the hole as well. Nothing. I suspect that there are layers on the inside between the back of that hole and hte void above the brake pedal. Any other options that people have used? I'm trying to get the switch wires for a light that I've already otherwise wired up and installed.

I believe that grommet ends up behind the MBEC somewhere...

I used the main harness grommet between the parking brake and MBEC. It's a tight squeeze through the boot.
(but I ran a large 8 gauge wire and 5X 10 gauge wires.. Bad picture, but the right side conduit runs to it.)

I've used that spot many times on many vehicles as well. Just be careful not to nick any wires!

Thank you all, will try this in a few days when I get a min to work on it again and report back.

I had an epiphany and ended up jumping the high beam wire to trigger the new light, no switch needed at all, just trigger brights.
