I bought a new rig and need to mod my HOTAS Cougar. Please help.

[MAYAman]

Hi, I want to floor mount the base of my HOTAS Cougar and have the handle up between my legs like it should be in a WWII fighter.

But I can't figure out what kind of connection the Cougar uses. When you screw of the joystick, it would be easy to have a section of pipe made and curved and the base put on the floor. But I can't figure out what kind of connection is used. It looks like a PS2 connection, but I tried a PS2 extension cable and it won't fit.

Does anybody know what kind of connection is used to connect the HOTAS Cougar/Warthog to its base? They both use the same connection.

thanks
