Default Forward alert radar wiring

Can anybody help me by supplying the wiring diagram to the forward alert radar that is used in conjunction with the adaptive cruise control. I cannot find any information on it in the main electrical wiring diagram document. Thanks.

Which model?

For reference, Speed Control is page 68 of the 2010 MY XF Electrical Guide.

Do you see the radar device shown in that document anywhere ?

@prolepsis That's brilliant, thank you. I was looking at the 2012 version and it doesn't show it on the adaptive speed control in that document. So I need to get the correct one I guess.

Thanks to the circuit diagram, I was able to find out that there was no permanent 12 volt supply on the radar sensor - due to a broken wire I guess - so I piggybacked it onto the ignition 12 volts supply wire and now all is working.😁
