Thanks Nat, plus four cool points.
Of course, even a controller cable is only a few feet long.  I’d really like it to have a multitap with a cord the length of an extension cable, rather than a mere three feet.   
  (As we know, multi-taps tend to malfunction when simply plugged into an extension cord.)
Do your instructions work with a cable from a Turbo Stick?  I have a broken one and they have pretty long cables.  Of course, then I'd also have to splice a PCE or Duo pin connector on the end. 

So…
1)  Is there an easy way to use your instructions with Turbo Stick cable and put a smaller Dou plug on the end?
OR
2)  Are there any cheap PCE/Duo controllers or joysticks that come with really long (6’ +) cables?
