The way I did it seems to have a really solid connection, when I had installed it I had SERIOUSLY slammed it a few times (probably harder than I should have) and they didn't budge. I did feel a little uncomfortable with part of the legs exposed and not sheilded (as the chip is right above them) so I cut up the foamish wrapper/pocket thing it came in to just cover each leg and a bigger piece to cover the X3 itself so as to help prevent something grounding it out.
