i want to replace some pickups on a crappy encore starter bass i have new ones but dont know how to wire them. the old ones have one black and one white wire on each of them connecting so one white and one black wire go to the volume pot. on the new ones they have one yellow and one brown wire, one green and one white wire. the white and brown are connected together(as i was told this was correct) so i have a green and a yellow wire to go to the volume. which way round should they go. any help would be great.
