I new to the community and I am preparing to change my first set of pickups in my new Mustang, but from the spec sheets I found online it looks a little confusing with all of the phase switching wires inside. Ultimately, I'm wondering do I even bother with those other wires or just focus on disconnecting the old pickup solder points and reconnect the new pickup wires to those old solder points? Any photos, instructions, drawn diagrams, or anything will be much appreciated. Thanks.
