The Ignition wire is pink/white
It is located in the 5 pin black plug at pin #3
I would not suggest splicing though....
Try this instead

The location on the 2011 CRD is not the same as in the above link/photo but you can easily find it with a tester. If you have trouble I can pop the hood on mine and post a photo tomorrow.
Sorry for posting links to another forum.... I got banned for doing that at another place. I hope it's ok here.
