anyone do a painless wring harness?

I just bought a 500 dollar Painless kit here locally, for over a hundred bucks. It was missing the box of connector parts, and claimed "short amount" cut off the dash harness. Well, it turns out the 'bay harness was cut a lot shorter.

Even so, looking at what I got, and what is in the missing plastic box, I sure don't see any 500 bucks worth of stuff there. The wire gauges "ain't" all that big, either.
