Common questions
Which wire is the 12 V constant on the XJ8 (X308), early head unit radio connector?
IC10 pin 10, wire colour NG (Brown with Green tracer). It stays live with the key out: this is the memory feed.
Which wire is the illumination feed on the XJ8 (X308), early head unit?
IC10 pin 3, wire colour RK (Red with Pink tracer). It follows the panel lights and dims with them.
What are the speaker wire colours on the XJ8 (X308), early head unit?
LEFT FRONT DOOR SPEAKER — pin 6, SR; LEFT FRONT DOOR SPEAKER — pin 7, SP; LEFT REAR DOOR SPEAKER — pin 8, BS; LEFT REAR DOOR SPEAKER — pin 9, KP; RIGHT FRONT DOOR SPEAKER — pin 17, SO; RIGHT FRONT DOOR SPEAKER — pin 18, SK; RIGHT REAR DOOR SPEAKER — pin 19, BW; RIGHT REAR DOOR SPEAKER — pin 20, KG.
What connector does the XJ8 (X308), early head unit head unit use?
The head unit sits on IC10. Jaguar colour codes are not the aftermarket standard, so match an adapter by pin number, not by wire colour.
Notes and caveats
Later cars differ. From 2000 the radio changes. The connector keeps the name IC10, but the wire set is different and a second connector, IC11, is added. Use the 2001–2003 sheet — the connector name alone will mislead you.
Premium system differs. On a car with the Premium system the speaker pins are not wired: the head unit feeds a power amplifier and the amplifier drives the speakers. This sheet is the Standard system.
Sides are absolute. Each speaker wire is drawn twice, as a driver-side and a passenger-side harness reference. That renames the harness, not the pin: the sides above hold for both builds.
No ground pin. IC10 carries no ground: pins 10 and 11 are both B+. Do not assume a ground here without checking the car.
Speaker polarity. Not marked. If a pair sounds thin, reverse it.
Both revisions checked. The 1998 and 1999 guides draw this connector identically, pin for pin and colour for colour, so the years above are checked rather than assumed.
Which head unit is fitted
Head units this fits. Alpine — LNC4100AA (AJ9800R), LNC4100BA (AJ9800A), LNC4100CA (AJ9800J). XJ8 / XJR (X308) 1997–2000.
