Pic 28 is installing the neck humbucker. You can see where the wire comes out of the hole previously shown into the bridge humbucker cavity (then down to the control cavity).
Pic 29 is all the hardware installed. Looks like a guitar now. Full length view is Pic 30.
My soldering iron sucks. It's only 25 watts. Everyone recommends a 40 watt. We'll see if I can make do with it. Pic 31 is a pic of the control cavity before soldering anything.
Pic 32 shows the diagram I'm using if anyone is interested.
