Which Jaguar Head Unit Do I Have? Part Numbers by Model and Year
The part number is printed on the head unit itself, and it is the quickest way to tell which one a car has — on the XK8 and the XJ8 the connector name does not tell them apart. Numbers come from radio-code databases and breakers' listings, not from a Jaguar document.

Part numbers are printed on the unit itself. They come from radio-code databases and breakers’ listings, not from a Jaguar document — but they line up exactly with the connector generations found in the factory guides, which is why they are here.
