Brake Controller?

Don't hold me to it, but I think the end that plugs in under your dash will look like this

Thanks all for your input. I just ordered a Prodigy P3.

It's an easy install with a Prodigy and a Ford Pigtail. The one I installed (Explorer but still a Ford) taught me that the chassis power to the Controller is NOT through the Ignition Switch. In other words, HOT all the time unless you pull the fuse (probably underhood) or disconnect the battery. I found out after I'd taped all the Pigtail wires together to fish behind the dash and the controller would not work once I was done.
So, disconnect Battery or Pull Fuse before starting the job. Good practice anyway.
I think Ford Pigtail is still Four Wires in a Square Pattern. If you have it before you start, it'll help you recognize the connector in the wiring harness.

What model did you get?

My 31 ft. E450 has a brake controller installed. MH used to haul a 4-place horse trailer. Works just fine with the wiring just like any other van would would.

Quite likely the E-450 is pre wired, Just need to add the controller and pig tail to plug trailer into.

I guess I need to rephrase my question. In order for the electric brakes to function on the cargo trailer, does the Tioga Montera require the addition of a brake controller, or will the electronic brakes function w/out one? I had to add one to my pickup in order for the electronic trailer brakes to function. I want the brakes to function regardless of any law.

Yes, you need a brake controller.
Tekonsha Prodigy P3 gets most of the votes here for a very good, yet not deadly expensive, unit.
It's a 4-wire hookup. The pigtail may already be under your dash if you have a fully wired 7-pin socket on the coach.

I have never seen a trailer with a brake controller onboard. Count on installing one. Others may come up with a preferred controller, but I won't because the one I like best has been out of production for at least 20 years. Someday I will find a modern one I like as much.

Yes, you need to install a controller for the trailer brakes to work.
