hi PunkRockerLuke,
in the diagram you linked to, it doesn't matter whether the wiper connects to the cap and the left terminal connects to the pickup black,
OR
the left terminal connects to the cap and the wiper connects to the pickup black.
the important part is that you use the left terminal and the wiper.
********************************************************
it would be just as valid to have one end of the cap connected to the pickup black, and the other end of the cap connected to either (a) the left terminal, or ( the wiper, of the tone pot.
in that case a wire to ground would be connected to either (a) the wiper, or ( the left terminal of the tone pot.
cheers,
unk
