Wanted! CD changer

Having just bought my first Disco II, somebody has removed the cd changer from under the passenger seat, but it seems it has an unusual plug left behind. It is black and rectangular in shape with 12 pins,(not all in use). Is this a usual cd changer plug as having found a Philips one on ebay it has a round plug.
Does anybody know if different make units had different plugs?
If anybody has a cd changer for sale in working condition, please let me know.
Thanks
Tony

Just found there is a wanted section, could somebody move this to that section pls?
Thanks
