dell ps2 keyboard, wire colour code?

Dell seem to use non-standard colours for there wires,

What I have...

Red
Black
Brown
White

Anybody have experience with this scheme...

I could take an educated guess, but it would make life easier if I knew...

Thanks,

Well I tryed a few configurations, and obvserved with the scope, as far as I can tell

Red ---------> VCC
Black --------> DATA
Brown ------> CLK
White -------> GND

is this helpful?

I looked at that before starting this thread. Unfortunately dells wire colour scheme doesnt conform to any of the schemes listed there.

Thanks,
