schematic for linking two guitars together

[dan lawson]

I need a schematic for a double neck. What i have is two small acoustic guitars using a D-TAR sadducer on both bridges. i need a schematic to install a vol pot on both (next to the bridge) and a 3 way switch so i can switch between both pickups. And i also want to be able to link both guitars together with a 1/4' cable so the whole thing works as one.
