If you're using IPE then this thread might be helpful. It also targets the PICKit3 which is likely different from the ICD3 but as eagleman pointed out you should be able to find the corresponding commands and options for the ICD3 and apply those.

My guess is that for newer devices you're going to have go "thru" IPE since that's where they add support for the new devices. But once you have it working from within MCSP+ it's a one click operation. Then again, I've only worked with the PICKit3 so I don't really know about the ICD3.
