Same with P bass pickups, they have been made and assembled all different ways.
Humbuckers are normally Wound CCW, and the north polarity is at the slugs.
Some wind them CW, and north to the slugs.
I always try to sell a set any more.
It simplifies everything Knowing how all pickups are wound.
I wind my P bass coils, both CCW.
Tie the starts together, and feed the output to one finish, and ground the other finish.
Fender does the one coil CW, the other CCW and ties a start and finish together.
Take your pick.
