quadro fx 3800 - 3d 3-pin connector

Does anyone know (or have the 3-pin-connector bracket and could veryfy)

how is the pin connection in a quadro fx3800

As anyway i do not have a 3-pin-2.5mm adapter (was not included in my 3d-vision set), i want to build a
direct cable from the graphic card to the 3d vision emitter

The connector on the quadra fx3800 is the same as the audio connector on a cd/dvd-rom

So if any reader here should have the 3d-connector-bracket, could you please tell me which 3 of the 4 pins are used

Thanks in advace
