What I tried was Black & Blue to ground, Red & Green to coil split switch (to be grounded for coil split) and White to hot. I tried switching the Black and the White and it didn't do it. I probably need to try Red and Blue to ground, Black and White to the coil split switch, and Green to hot. That will put the north and south start together for the coil split, and the north finish to ground and the south finish to hot. Does that sound right? The bummer is that it is a strat style with pickguard, so changes aren't easy without sacrificing another set of strings.
