Pretty sure I've finally found a source for the male MAF sensor connector that allows for MOQ of 1 (and it's cheap to boot).
This is what I'm talking about:
I've ordered a couple to check and confirm, but if it is then this is the missing piece for people to be able to build their own harness extensions (and IAT relocation extensions I guess, not that I think they're good idea) without having to pay Turner mark-up. It also means anyone wanting to do what I did (keep the MAF connector and wire up for MAP sensor) doesn't have to buy a Turner extension just to then hack it up to add on the Bosch MAP sensor connector, etc.
I'll wait til these arrive and I've confirmed and then put up a post with all the various part numbers needed to do this.
