O.K., try this, connect the pocket wizard to the Nikon screw lock, use a paramount cord. Now when you connect the Household side to the Pocket Wizard & try it.

If it solves the problem, fine. If it doesn't, as I suspect, reverse the HouseHold connection. I know, that because of the polarized plug, this won't be easy, or maybe not even possible, but try. I think, that you'll find that this is a polarity problem. You may have to file down the wide blade of the cord, you just bought. If you do, use liquid paper, to mark one side of the connection, on the cord & the matching side on the Pocket Wizard.

Remember to try both Pocket Wizards & both cords. The one connecting the camera to the PW transmitter & the one connecting the flash to the PW receiver.
