Default JR pinout

I bought a Turnigy 2.4 RF module from Hobby King. This module is for their radio but it will also fit a JR transmitter.
I want to use it to convert an old transmitter to 2.4GHZ. For that I need to know the pinout of the JR transmitter to the plug in module so I can fabricate a cable.
Can you provide me with that information?

I learned from another post that you won't release this information. If you think I can't find it you must be very simple minded. All I have to do is find a JR Radio and make one measurement. All you are doing with this attitude is strengthening my resolve to never purchase one of your products.

Just want to add, the +6 volts on pin 2 is only used on the fixed frequency transmitter module but is not required for the JR Synthized module and off brand modules(non-JR).
Pin 1 PPN is 3.3 volts peak to peak and is a positive going pulse 0 to 3.3 volts positive.
FYI Not to get off the subject but those of you installing lipo batterys in transmitters & receivers made for nicad batterys should install a small voltage regulator down stream of the ON - Off switch to power your radio to pervent over stressing your electronics. ( 7.4v down to 6v and 11.1v down to 10v will give you many good years of service,
