Most of the the work that I have done has been will GM's E38 ecm. Below are the two connectors for the E38. They don't seem to list a cavity plug at all. I have completely stripped a few factory GM harnesses any I've never seen a cavity plug in a factory setup either. There is a build in seal in the connector that seals around the wire when you insert it. The wire openings in this seal are very small. You could just cut up some scrap 20/22 gauge wire and insert it in the unused spots.
