So if I follow you correctly:
- use the black wire from the neck pickup instead as the blue in the diagram
-green+screen from neck pickup is signal ground on the first potentiometer
-use black wire from the bridge pickup instead of the red on the diagram
-green+screen from bridge pickup as signal ground for second potentiometer
-tape up red/white wires
-Use rest of diagram
But how to make ground with the bridge? there is no internal hole to get there?
