I have just bought a used pair of Fender Lace Sensor pickups to "upgrade" my Jazz bass. I am a little confused by the wiring and also which is neck or brdge position. Both pickups appear the same from the front, from the back one has a red sticker the other a green. The one with the red sticker has three wires(green,white,orange)all three are twisted together and terminate in a connector. The one with the green sticker has five wires. One orange and one orange/black twisted as a pair, one white and one white/black and one green twisted together and terminating in a conector. I assume I will have to cut off the connectors and do some soldering, but what goes where? Why does one have five wires? Is it a split coil pickup? Do I have a mismatched set? Any help much appreciated.
