This most likely is "over the top" for most modelers, but I decided to find out exactly how the "plumbing" on the P-47 and other American fighter headsets went on the real airplane. I found a picture today online, and now I know how it worked.
For those interested, the leather or cloth helmet (winter or summer) had an earphone for each ear. They were connected with a cord that then went down about 12 inches or more to a male red phone jack plug. The red phone jack plug was then in turn plugged into a Y-harness and plugged into a female plug on one part of the Y harness and then the other part of the Y harness had a special connector to the oxygen mask microphone. This now connected, became a single larger cord with a larger single male end plug that went into a receptacle on the left side of the cockpit side wall.
I'll attach a photo of the finished changes I did on my pilot, and a photo of a mannequin that shows how everything went together. I am happy I solved this little question in my mind, as I always wondered how these cables all hooked up.
Cheers
