Remove gold grounding tab on PCM

[moto_shop]

I had the same question when installing my chip. This has very little to do with common sense or nitpicking and more to do with the fact that people dont want to ruin an expensive PCM or break down a long ways from home. Most people, including myself, have no idea how electronics work, and when its not spelled out in detail, we get a little nervous. The question was asked because we're not the experts and haven't installed hundreds of these. We want to make sure we're doing it right, which shouldn't imply we weren't gifted with your and Bill's level of common sense.
