Hey bud...I too asked this question not too long ago and was shocked when I found out where it was...
Standing infront of your engine bay, look towards the rear left side (not firewall) and you will see a slant, black plstic cover...remove that, and you will see the horrid.
What are you tryin to protect it from? Water? Electrical tape would not be enough and might even make it overheat (as a computer geek, I enjoy the satisfaction of knowing all my electrical-anythings are running cool)
One of my future mods is a relocation to the glove box.
