[font=trebuchet ms]If you have a clear schematic, I don't understand what you're having trouble with? Both of my Yamaha SBG1000 guitars (like LP doublecut) are wired with series/parallel for both pickups, plus phase selection. I don't use coil-taps because they don't sound very different from the parallel connection except that they are noisy.
Anyway, e-mail me through my profile, and I'll try to help you out.[/font]
