You'd need to energize the harness to test for anything other than continuity. If you've got continuity on any one pin then you know the ground is good, if you've got continuity all around and a problem still exists it's not in the harness. In my experience and in keeping with Occam's Razor, solving a trailer harness issue often involved a simple grounding problem.
