if the pickups are already active then you should be able to just swap the old ones out for new ones and reconnect the wires the same way, one pickup to each volume then to the preamp just like they are probably already wired as long as your bass already has the right pots for active pickups if not youll have to swap them out for the pots that come with the emg's witch is a simple task because the emg stuff is all prewired with plugs.
personaly I would get rid of one of the volumes and get a blend controle for the pickups in wich case you run bolth pickups to the blend then to the volume-preamp.
either way you don't need the tone controle, you use the eq preamp instead.
I put emg twx pickups in 2 of my spectors and I love them but then you have to use 2 volumes(push/pull pot switches for the coil taps) unless you want to do some serious rewiring of the switch harness to add a coil tap switch but I do have pics to help if you want to go this rout.
