From the firewall the cable just goes down and back. You can pretty much route the cable wherever so long as it doesn't get too close to anything hot or anywhere near moving stuff. I assume you can see how the cable end goes through the bellhousing and such.
There should also be a little metal sleeve on the cable, I don't know if you got the metal hook/bracket that bolts under the hood, but that also helps a bit with direction if you do. I'd give you pictures but I don't feel like jacking up the car at the moment.
