I just got a set of Fender Original Jazz pickups. They come equipped with a base plate that is glued to the foam that the pickup sits on. The base plate has a wire soldered to it. This wire is in addition to the 2 wires coming from each pickup. Since other jazz sets don't have this base plate wire, I am wondering if I don't need to solder the bass plate wire. I am guessing the wire is an additional ground wire. The bridge is already grounded on my bass. I am simply swapping pickups. The instructions that came with the set do not reference this wire at all, and I can't find anything on this topic. I searched using Google and searched TB for help. Anyone know the answer to my question? Thanks.
