Hi, so I have a squire strat that I'm refinishing and I bought a Fender Noiseless pickup for the mid position. My old pickup only had two wires coming from it (black and yellow) while the new one has three (black, yellow, and green). Now I assume that the black and yellow wires are the same, but what do I do with the green one? Is it just a ground? I have looked at the wiring diagram thread but I can't make any sense of it.

Thanks, but that only shows two wires coming from the mid pickup, I need to know what to do with the third (green) one.
Ok, the wiring diagram for the ash stratocaster has three wires and it looks like both the black and green wires are going to the ground. Is that correct? It doesn't seem right to me but I don't really know.
