Be VERY careful but you can drill a hole in the rubber gromet that surrounds where the throttle cable goes through the firewall. That is where I have my CB coax cable going through.

That's how we Jeep guys develope our skills....Making up for the shortcomings of those overpaid 50 pound head engineers....

I found the easiest way to make a nice hole thats the perfect size is to use a nail on the end of some vice grips, heat it up with a little torch and poke it through melting the rubber and creating a nice little hole to fish stuff through.

i know you have solved it, but for anyone else looking at this in the future:
It is super easy to use a wire coat hanger and fish it through by the hood release. there is no extra holes, and you are right by the fuse panel to wire it in!

There`s a round hole about the size of a quarter already in the firewall of my 1994 Cherokee under the dash up in the corner to the left of the steering column..I believe it had a rubber grommet around it at one time but nothing was going thru it...Maybe it was meant for some option that my Jeep never had?..I used it also to run power wires for a CB set up.
