There are two knock sensors located on top of the Engine, approximately in the middle of the 4 cylinders at each bank.
To get access to the sensors the black plastic engine cover with the "Jaguar V8" imprinted on has to be removed.

There are two types of knock sensors.
The "old" ones that are of a "screw-in barrel type" and the newer ones that are just bolted on.

I describe the replacement of the bolt-on type knock sensor on Bank 2 in the following documentation on a 1999 XJ8 AJ27 engine.

Be careful!
Knock sensors are piezo electric devices that are very sensitive! If dropped, over-torqued or struck they will probably be destroyed.
As knock sensors are sensitive to a sudden temperature change they are also easily fractured by steam blasting a hot engine.
So handle the knock sensors with great care and let the engine always cool before fitting a new sensor!
