sorry for late reply, been away from the interweb for the weekend!
the pdf is the standard humbucker wiring code for dimarzio (yours is a standard wired 'bucker but in a single coil package), what colour wires have you got on the p'up?
MikeAnsty is absolutley correct, 250K pots are generally used for single coils, by changing the volume pot to a 500k you will get a better response from the humbucker, but will 'darken' the tone of the remaining single coils p'ups. This can be slightly remedied by changing the capacitor on the tone pot for a 47k orange drop cap, but thats really only to your taste and if you want to go that deep into 'chasing that tone' !!!!
