I have been trying to find a wiring diagram with one humbucker that has two wires coming from it, has one volume, than just a output jack. Can anyone help?
Just make sure that the black in this diagram is the output from your pickup, and the green+bare will be the ground. Ignore the red+white series link.
Actually, since there is just one pickup, you can even get the wires from the pickup reversed and it won't make any difference to your final result.
