That’s where my 47 fuse block was located. Just left and below the harness grommet. My truck had all the cloth covered wire still intact when I bought it. Although very stiff and bare in some spots. As you can see there were no other holes in my firewall. I mounted a new fuse block where the old one was.
You are correct fine sir. I stand corrected, and have edited my previous post to reflect that.
