I want to put these Fender SNC (FENDER NOISELESS SAMARIUM COBALT) in my strat.. I want to know why they have left some of the solder points unsoldered with no wires coming of them?? in the diagram it shows there being 3 wires coming of each pickup but my only one of the pickups actually has three wires coming off it... Am I supposed to supply my own wire to each pickup?? whats going on?? I though this would be easy!
