Wiring thru firewall

I’m putting spotlights on the back of my trucks bumper. How did you guys run the wiring harness from the battery thru the firewall I am putting the switch on the dash.

For a 1/4" hole, use a .22. You get a 3/8" hole with a .38 or 9mm, and use a .45 to get a 1/2" hole.


Or better yet, just poke your wires through the rubber grommet for the speedo cable.
