I knew there was one in there as I'd replaced it a couple of years ago, so off came the parcel shelf and sure enough, the bulb had simply dropped out and was nestling safely between the centre console and carpet. No need for a new one, this time I made sure it was securely fitted.
Whilst I had the parcel shelf out I decided to see why the radio would not sit right back in its slot, so out that came, I then noticed for the first time a small toggle switch cunningly hidden away behing the dashboard, clearly a previous owner had an alarm of some kind which had latterly been replaced by a Clifford immobiliser.
After checking with a multimeter that none of the wires were powered with the ignition on or off I traced the wires back through the centre console behind the radio , some to the relay board and some to the engine compartment. Fortunately, this is where they terminated behind the sound deadening on the bulkhead, being blanked off with insulating tape.
After some careful extraction, removing scotch lock connectors from the loom, the picture below shows just how much there was. And the radio? - well it now sits properly fully back in its slot.
