Pickups wiring MOD to parallel/single coil

[Jonathan Esquivel]

Hi!!! I recently bought a pair of Smith pickups to upgrade my Yamaha Nathan East, and I love the sound!!! I read about the parallel/serie/sc switch posted by Rainer, and I want to try it... Anyone do this? How it sounds??
Another issue with the pups: I have to rewire them to install the switch, but I don't know the polarity of the coils.. what can I do to know wich pickup coils it's the positive/negative??

Thanks!! And sorry for the questions...
