Which model years this covers
This pinout covers the XJ8 (X308) of 2000, 2001, 2002, 2003. One table serves every one of those years: within a head unit generation the connector and the wire colours do not change.
Other years of this model carry a different head unit — 1998–1999 MY on IC10. See that pinout.

Common questions
Which wire is the 12 V constant on the XJ8 (X308) radio connector?
IC10 pin 1, wire colour NG (Brown with Green tracer). It stays live with the key out: this is the memory feed.
Which pin is the ground on the XJ8 (X308) head unit connector?
IC10 pin 6, wire colour B (Black).
Which wire is the illumination feed on the XJ8 (X308)?
IC11 pin 20, wire colour R (Red). It follows the panel lights and dims with them.
What are the speaker wire colours on the XJ8 (X308)?
LEFT FRONT SPEAKER + — pin 3, YU; LEFT REAR SPEAKER + — pin 4, WU; RIGHT REAR SPEAKER + — pin 5, WG; LEFT FRONT SPEAKER – — pin 8, YR; RIGHT FRONT SPEAKER + — pin 9, Y; RIGHT FRONT SPEAKER – — pin 10, YR; LEFT REAR SPEAKER – — pin 11, BW; RIGHT REAR SPEAKER – — pin 12, BW.
What connector does the XJ8 (X308) head unit use?
The head unit sits on IC10 and IC11. Jaguar colour codes are not the aftermarket standard, so match an adapter by pin number, not by wire colour.
Notes and caveats
All four years checked. The 2000, 2001, 2002 and 2003 guides draw both connectors identically, circuit for circuit. Three colour codes differ on a 2000 car: pin 8 of IC10 is OY and pin 12 is BO, and pin 17 of IC11 is UY.
Earlier cars differ. On 1998 and 1999 cars the radio sits on IC10 alone, with a different wire set. Use the 1998–1999 sheet.
Power feeds. Pins 1, 2 and 7 of IC10 are all B+, from fuses 20, 21 and 24. Which of them is ignition-switched is not stated.
* Pins 8, 10, 11, 12. The guide contradicts itself here. From 2001 it prints YR on both pin 8 and pin 10, and BW on both pin 11 and pin 12, and two speaker channels cannot share one colour code. The 2000 guide prints OY on pin 8 and BO on pin 12 instead, which leaves all eight speaker wires distinct. Which of the two is the car is not settled by the guides; check these four with a meter before cutting.
Which head unit is fitted
Head units this fits. Alpine — LNF4100AA (AJ2000W), LNF4100BA (AJ2001W). XJ8 / XJR (X308) 2000–2003.
