Default Firewall wire passage?

I'm in the process of adding some gauges to my 93C4 and i'm trying to figure whats the best location to run the wires. I know some people don't like but i don't need your opinion. So if anyone has done it what rout did you take? Thanks to all.

It depends on how many wires and how Heavy they are. for a couple of smaller wires I have seen People run them thru the center of the hood release cable grommet.

Also though never seen it or done it maybe a well placed hole with grommet drilled thru to the side of the steering column plate on firewall.

I wanted to route just 1 wire into the cabin. I ended up drilling a small hole in the drivers footwell. Chevy buttoned up things pretty well on the firewall.

Yes they do, it's hard to be discreet or Noninvasive
