4 - neck pickup coils in parellel.
Parallel is as opposed to series connected, where the coils are connected end-to-end, with the signal going from one to the other.
In parallel, the signal is coming from both coils simultaneously (as though they were both separate pickups [which they are...]) which gives you a lower output, with more high-end content as compared to series connected. It's closer to a single-coil sound, but is still hum-cancelling.
There are wiring diagrams available, if required.
Hope this helps.
