I am about to buy fender lace sensor humbuker. I noticed that it had three three different wires running off of it but my singles have only two. could some one tell me how to hook it up before i get it and screw the whole thing up trying to do it myself. Sorry if thjis is some dumbass question but this is the first time I've tried to trade out my pickups.
One of the wires is probably a ground. It should tell you on the packet, but the earth wire is generally the plain copper/steel wire that is wrapped around the two internal insulated wires. Just solder the ground wire to the ground insulated wire. It should have instructions on the packet anyway. I don't see how you could wreck either your amp, your pickup or your guitars wiring by doing it wrong...
