The controls have nothing to do the the pickups. Pickups are wired into whatever sort of circuit is chosen.
If there is a volume and tone, and not bass/treble, then that sounds like a standard passive control scheme with passive pickups. If you choose active pickups, you will need to replace the pots with 25k or 50k values, due to the lower signal impedance of active pickups.
