I came across a great deal at a local store a few days ago and ended up with 4 brand new COP's from what I was able to track down as the COP's fitted to the 2003 Jaguar XJ8 4.0. My only problem is that I cannot locate any information as to what each pin is. (4 pins in a jack on the side). Does anyone have a source of information on these modules? I got them new in the box for $5 each.
