Sorry to bring up such an old post but I would love to see your take on the nighthawk wiring without the floating coil issue. Small world, Might be right around the corner from ya here in Jacksonville too!

Re: Nighthawk-style wiring (SuperSwitch content)
Whew! That wiring makes my head spin.
Basically, what you're saying in the first paragraph is correct. Your color translation is good-to-go. On a Duncan humbucker, if you connect red/white to ground, you'll get the stud coil. Red/white to "hot", or output, will give you the screw coil. I'm not sure which would be which with the pickups in that diagram.
However, they are doing something that is less than ideal in that wiring scheme. (If NightHawk owners aren't experiencing excessive hum and noise in the single mode, then you can ignore this.)
In the above wiring, when a pickup is split, it leaves the unterminated coil hanging out on the "hot" side of the circuit. Like a "noise" antenna. Look at the following diagram:
In the top two figures, you de-select a coil by shorting it out. In the third, you leave one coil hanging, but it's hanging on the ground side of the circuit. Not ideal, but probably not a problem. (Still could be if you use a very long guitar cable.) In the last one, the unused coil is hanging on the "hot" side of the circuit. As is done in your NightHawk wiring.
Let me study your diagram some more and see if I can come up with a better way to do it that preserves the full functionality, but helps in the "noise" dept. (Using Duncan colors, of course.)

P.S. Due to gas cost these days, I was trying to wait 'til I was making a PO run anyway to send these out. If nothing comes up, I'll get them out before the week is over.
