series pickup wiring - advice please

[Geek99]

I have some new jazz bass sized humbucker pickups. They are sealed and the coils are visible at rear so can see one black and one white coming from each coil.
There is also a yellow shielding wire, I know what to do with that.
I want to wire in series as my cij jazz is naturally quite bright and trebly.
I know white is signal and black is earth; 1 white goes to the pot and 1 black goes to earth.
Can someone tell me how to connect the coils properly ? Do I just take the spare white and black and join them ?
Does it matter which black and which white I choose ?

Thanks

Edit : each pickups coils in series, not two pickups in series together

white neck wire to vol pot lug
black neck wire to white bridge pup wire
black bridge wire to earth
Now you have to use both together as a double humbucker unless you put a switch in to allow you to choose neck, bridge or both.

Not sure that's right as that would put the two pickups together in series? Each pup has two black and two white.

ah, soz, missed that bit, join the internal white and black together for each coil pair, to complete the humbucker circuit.
Normal guitar humbucker with 4-conductor wiring will have a red, white, black and green plus shield.
If you want to coil-tap it then the red and white go to a switch, otherwise they get soldered together and the pup is wired normally with green as live and black as earth.
Note- different manufacturers use different colour codings, the above is normal for Seymour Duncans.
