hello, I got a new darkburst pickup, I am going to replace a 57 classic, how do I wire it up? The 57 classic has only a black wire and a ground. The black wire goes to the volume pot lug, and the braided cover wire goes to the volume pot caseing. The new darkburst pickup has a red and black wire AND the braided ground wire on the outside. How do I use the extra wire? Where does it go ? I am guessing the braided ground AND the red go to the volume pot caseing? And the black goes to the volume pot lug? One extra wire and I turn into an idjit. THANKS !!!!
