Is anyone able to help me locate a wiring diagram for early series basses (74/75?)  I'm in need of troubleshooting help and wanted to see what should be connected where in terms of the wires coming into the electronics cavity from the pickups, humbucker, tone and volume, pickup selector know and boost cut switches. Thanks, Todd

Email Mica and I'll bet she can mail you one. You can also do a search here on the forum and learn a lot of info, esp. from the photos you find.
