Own a 1995 XJ6 sport and have just wired the stereo in properly(a previous owner snipped the wiring plug off) - wiring details supplied online is as follows:-

Constant 12volt + - Brown/white
Switched* 12volt + - Green/orange
Ground - Black
Antenna Trigger - Green

Front Speakers

Left + red/white
Left - red/green
Right + pink/white
Right - pink/green

Rear Speakers

Left + red/brown
Left - red/green
Right + pink/yellow
Right - pink/green

*I found no switched live - the green/orange wire was dead with and without the ignition switched to acc - I took the live from the cigarette lighter and it works fine
I also spent a great deal of time with the speaker wiring - it looks straightforward on paper but the reality can be confusing
I found that using a multi-meter helped
Also, checking the Haynes workshop manual revealed how much the wiring can differ between years and models
Be careful because the fuse for the live also protects the boot unlock button and it's located in the boot - see my posting on the forum under "Bodywork" for a solution to that

Welcome to the forum Stuartie. Sorry but I can't help you on the wiring. I do have a couple of hi res pictures of the wires and the plugs connected to the Jaguar radio. If you know what you are looking for they might help.
I'd be inclined to source a radio harness from a breakers, solder it together to what you already have. That way you'll esentially have the normal Jaguar harness and plugs. Then you can buy an ISO adaptor lead to fit most other head units.

Thanks for the reply. Yes that would be extremely helpful - my e-mail address is stuarthalley@btinternet.com
Kind regards
