After extensive use of the search button, getting confused with various part numbers and researching the how to guides I've just replaced the Ashtray with the None Smokers Pack. I also extended the wiring from the Ashtray (I adapted the connector off the Ashtray to avoid cutting the connector out the car) and fitted the light and cover under the Double Din, still quite impressed as its only the second mod I've done so far. There is something about that feeling of looking at the finished product and knowing you put all the parts in yourself.
Anyway, whilst the Climate Control unit was out I noticed on the back of the Credit Card / Coin Tray there looks to be an electrical connector, but nothing plugged into it. The tray was fitted to my car when I had it and I only noticed recently it doesn't light up (I didn't notice till I read about it on here). Should there be a connector lurking about to plug it in to? I had a look for one whilst the car was in bits, however couldn't see anything. I just wondered if it would be taped up somewhere out the way.
