mine turned up the same( promo priced after market one from ebay), the second wire is not wired through, but if you look closely, there is a sensor soldered on, but it doubles back on itself, and not across the gap. i initially thought it was faulty until i took a closer look and was happy with the build, installed and now my surging has gone away.
I am convinced that a faulty MAF can hide and or enhance other problems, i.e. i still think i have a problem with the boost modulator, although it appears less now with the new MAF.
all good fun, and now i have a spare(that was on my car for only about 8 months before i bought this new one) that seems to function ok, but i am still not 100% on it.
still seem to be using more fuel than i would like though. :/ approx 700klm/tank
