here are some pictures I need to know how to wire this together anyone know how? It's a Fender Precision Active, 1993. There is a yellow, white and black which I know is a ground, but I don't know what the other wires are for. The white wire is a constant power but the yellow I have no idea? The 6 pin switch is my problem I can't figure out how to wire the two pots and the amp into it.
