2001 Mustang Cobra - No electrical power at all

So I installed a replacement 2001 power distribution harness and.. no power what so ever to anything in the car. I'm getting 12v at the BJB post, I have good continuity between the fuses and the BJB post as well. The grounds that connect at the BJB (yellow/black and black on two pin connector) check out.

Any ideas? It's gotta be something big and obvious, I would hope.

Car was doing fine on the 1999 power distribution harness I replaced. I will say the connector in the driver side fenderwell is strange. It seems loose, but I tightened down as far as I reasonably could. Wiggling it doesn't fix anything.

Ok, fixed the problem. let this be a cautionary tale to all. When I removed the old power distribution harness, the red pin-centering plastic piece on the connector in the driver side fender well didn't go with it. So, when I installed the new harness, I double stacked those pieces, which prevented continuity and ultimately broke that connector. I fished out all of the broken bits and put it together. Problem solved.

Now I have a lot of soldering to do, probably going to cut the broken connector off and replace it. Unless I can figure out how to repin it.
