The quickest and easiest setup for a small trailer like that would be to install a Surge Brake setup.
In my experience, once Surge Brakes are mounted, bled, and maintained, it would be easy to hook up and go. But if fitting brakes to a trailer that is not equipped? Run wires, not tubes.
If the trailer has brakes, they have to work to be legal. Do you need them? What is the GVWR of the 5th wheel? What is the weight of the 2 trailers, loaded and going down the road? Bet the other brakes will be overloaded if you don't have brakes on the last trailer.
If it was me, I would run a wire on TV so the AUX pin on the plug got same signal as the brake controller does. I would mount a 2nd controller near back, inside of 5th wheel. Use power from 5th wheel battery, and control from AUX. Before mounting the 2nd controller I would hook it up in TV, hook up the trailer, and adjust the settings. Mounted in the 5th, same settings will be good.
You could get by with a 5 pin connection between the 2 trailers, but I would use the standard 7. Likely cheaper, need no change on TV to tow w/o 5th wheel, and only need 1 spare.
BTW, I understand that most of the controllers we use could control the total number of axles on both trailers. But I bet the design expects all the axles to be loaded near the same. Just hooking the other trailer to brake circuit of 5th wheel likely would slide some tires
