hi . I am building my first kit and really enjoying myself. the soldering is going well from the wiring diagram.all the pot wiring makes sense. it is a IB -6S. left handed bass. my question is that the diagram seems to show only one wire coming out of each of the humbuckers. what i have is 5 wires. 1 white, and a red and green fused together, and a black and bare fused together. is there another wiring diagram I am missing?
