I apologize for what appears to be a lot of internal dialogue, but some of this is me talking myself back through something that was planned and worked out 6 months ago and I've done more reading about the wiring and how everything works, which has raised some new questions. I've made a few minor changes to the equipment as well.
Looks like I bought a pair of 30A outlets that are the wrong ones.
Just so I have this straight...I'm running a 4 wire service from the breaker to a 4 wire outlet mounted to the wall in my garage near where I'm going to brew.
A four prong plug is going to be wired into the spa panel that plugs into the previously mentioned outlet. A 4 wire socket is going to be installed/mounted in the spa panel. A four-prong plug is going to be wired into my control box, which will plug into the outlet in the spa panel. Basically, wiring the outlet and powering the spa panel through the outlet, and duplicating that outlet in the spa panel after the GFCI breaker makes the system essentially portable. If I move, the only thing I'd have to do is run a 30A 4 wire service to an outlet I install in the new place, plug the panel in, plug the control box into the panel and I'm good to go, right?
Next thing to confirm...I have 2 30A 6' long cords. I need to get the correct 3 plug outlets to match them, and those outlets will be mounted on the side of the control box which will supply power to the heater elements.
So, at this point, I need to buy a pair of 4-prong outlets, a pair of 4 prong cords, and return the two incorrect 3 prong dryer outlets.
I have a pair of these cords to power the elements:

And they don't fit with these plugs:

That all seems to make sense to me...however, it's not what P-J has the parts list for me or the wiring diagram. Diagram appears to have a 4-wire supply to the terminal blocks and it goes from there.

Anyone have some insight?
