Many thanks for this one. It really helped me out. The hardest part was getting the wires out of the big CCC plug. As has already been said, after removing the blue clip put a flat blade/terminal driver into the plug end and then push/pull on the cable to remove.
For those with an auto box, put the car in D before disconnecting the battery otherwise you'll not be able to get the CCC out. I found this out the hard way.
