Technical Speed sensor wiring colours

[J412100]

Please can somebody tell me what colours on the speed sensor correspond what colours on the wiring loom?

I have three wires coming off the speed sensor in the gearbox:
Yellow
Blue
Brown

The loom wires are:
Orange/White
Grey/Red
Black

The pins have come out of the socket housing on the sensor side so I'm unsure which wires correspond to the loom wires.

Any help would be greatly appreciated.

the wiring diagram only shows the orange/white and grey/red wires going to the sensor, the sensor's loom colours are not shown in the wiring diagram. sorry.
