920d Custom’s S7W 7-Way Wiring Harness a versatile wiring harnesses for a Stratocaster. You get your standard 5-Way Stratocaster pickup selections, along with 2 mini toggles. One of the toggles is a "neck-on" switch. This allows you to add the neck pickup to any position of the 5-Way selector switch — giving you bridge, neck and bridge, middle, and neck pickup combinations. The second toggle is a coil split that will split your neck and bridge humbuckers, giving you a more traditional Stratocaster single-coil sound.
