Exactly what I did, except I have a 0-gauge wire running from my battery. Basically had to use a 3/4" drill bit on that cover for the clutch.
For those who are reading this, it's not a good idea to run anything in line with your fuse box, and it's actually much more reliable to utilize a direct link to your battery.
On the same token, to reduce ground loop and interference through a car audio system, consider running a direct line using another distribution block from your ground terminal on your battery. It provides your amp, stereo, TVs, etc. with a good, solid ground.
