Gauge install

[CtChevy427]

Tomorrow I am planing on adding a Pyro and Boost gauge to the truck in the sig below. Where on the firewall is the best spot to poke everything through?
Picture would be great. Thanks

You should have a rubber grommet below the master cylinder, on the inside it's approx behind the fuse panel.

The REAL big rubber grommet on the Driver's side firewall...just like Jay said. There is also another one on the passenger side firewall mid way down. I am laid up with a broken ankle now so, no pics.....sorry.

I drilled a hole and placed a grommet in it in the firewall up above the accelerator.
