How to: install the EVH D-tuna

Before trying to install my own, I noticed nobody had posted a "how to" vidya on the D-tuna. So I figured it out without breaking anything, and did it over again just to pass along to others... and to show how easy this is to do. IF YOU HAVE A FLOATING FLOYD OR FLOYD-ESQUE TRIM, REMEMBER TO BLOCK IT. That&make this a bit easier on you folk.
