You might take a look at Andy Karmy's website (www.karmy.com\rv9a). He has lots of pictures of the wiring on his RV-9A, including a drop-down fuse panel on the passenger side. I'm doing similar on my -7A, and generally following recommendations from Bob Nuckolls for a main bus and essential bus architecture. I have put some loads on circuit breakers instead of fuses - the important stuff that I may want to give a second chance to in flight if the breaker ever opens.
I'm not yet ready to say that this fuse panel is the best solution, as it's still a work in progress.
Some have asked about access to where I put the fuse blocks you can see in those pictures (behind sub-panel and on rib forward of sub-panel). I've considered adding an access panel, but so far I've found it's not really that hard to get at those fuses and wires. Although it was difficult reaching through all that to buck those last few forward top skin rivets....I accidently pull tested a power wire to failure at the connecter while trying to get that last skin riveted so had to repair that.
Everything's working very well so far with inspection complete, taxi testing & electrical testing done, first flight soon....
I would definitely use color coded wire. Red for Power, Black for ground, yellow for signal, and other colors as desired. Use a "Forrest of Tabs" from B & C for ground and ground everything there. Vern Little has some great avionics electronics at very reasonable prices. I used his AMX-2A and it works perfect. His service is The Best. Check out http://www.vx-aviation.com/ for his products. He also has an RV project website at http://www.vx-aviation.com/rv-9a/. There you will find some great ideas. Note the circuit breakers he uses. Very panel friendly and way less than klixon.

(BTW, the quick-disconnect is great stuff, just take the panel home and do some modifying, much more comfortable than in a frozen hangar..)
