Keeping it simple makes things easier with the ES kits. It's hard to tell from the pic, but if you are doing one of the ES kits with a center block, it looks like some, at least, of the holes may be too close together. Making the harness pretty close to exactly the right size will make it much easier to get the right things to come out of the right holes during installation.
Also a good idea to take Simon's advice and draw the F-hole about where you think it goes. I initially wired mine with a cable running right across the F-hole to the lower bridge pup volume control, and then ended up completely redoing it.
