Speedometer sensor location

[c.morewood]

This is probably a really simply answered question.. But I can't find the answer.
T has a speedo that doesn't work. It used to move when stationary and revving the engine but no more.
I've had the binnacle apart and made sure the connections are good so I can only asssume that its the sensor or its electrical connection thats playing up so I've ordered a replacement.
I've tried looking online and can't find any decent pictures of the location of the sensor.. I had a good look today whilst bleeding the brakes after hydraflushing, but I can't see where it goes into the gearbox.
I'm guessing it must be underneath the gearbox and I can't see it with the undertray in place.
Does anyone have a picture of the location please?
Thanks,

Sensor is on the final drive housing Chris, just above where the RH (long) driveshaft enters the diff housing...

Feel for it initially and look for a three pin connector going to it...

From under, access is not too bad... Usual safety precautions apply.

Speed sensors are common right across the 90s PSA range...
