Audi A4 or A6 (or Hella) - Accelerator Pedal Pinout

Can anyone tell me where I can get a pinout description for the Accelerator pedal used in the Audio A4 or A6?

A strange request I know, but I am using this pedal for purposes other than in an Audi and I appear to be unable to find info. on it on the web.

If anyone knows the connector type (and source) it would be much appreciatted as well.
