I'm mounting gauges, wheres the bestplace to run through the firewall?

[Sudden]

I know I've seen this somewhere but I can't find it. I've searched but had no luck. I've mounted a pillar pod with boost and AFR.
Where's the best place to run these through the firewall.
TIA

There's a grommet on the passenger side that works great. It comes out below the dash.

through the passenger side grommet, or through the steering shaft grommet which exits under the brake booster.
