Trailer Brake Assist??
My 95 F350 came equipped with an electronic brake assist. I know nothing at all about how it functions (yes, a nubie). Its a Tokansha Voyager XP.
Anyway, I went to rent a small Uhaul trailer, and they used an adapter to plug into the harness at the rear bumper. The connector is round and has multiple blade connectors. The Uhaul trailer lights did not get any juice.
Could this be related to the trailer brake assist? Can some explain how it works and what connections the head-unit should have? I guess a wiring diagram would be best, once some explains what functions it controls and how do I use it.

Your Tekonsha Voyager is better known as a Trailer Brake Controller. It's only job is to run a set of electric trailer brakes. It sends a variable voltage to the trailer based on how hard you are stopping or how far you slide the manual lever.
As for your Uhaul. The controller is not the cause of your problem. Uhaul doesn't use electric brakes on their trailers because not everyone has a controller, they use a hydraulic surge type brake instead.
I would check out the plug on your truck first to see if it's working properly.

If your 95 had a factory towing package, you may have some relays and extra fuses for the trailer lights under the hood.
Otherwise, your trailer lighting is probably spliced into the harness in the rear.

So are you saying that the round multi-pronged plug is ONLY for brake control and not a power lead for the lights?
The plug is connected to the factory wiring harness using factory style multi-lead connector. Its a plug and play connection. Maybe I am making the wrong assumption that the bumper plug has leads for a brake controls AND for lights?

They usually have a small extra box under the hood. From your second post is sounds like someone bought a t adapter and plugged it into the rear harness of the truck. If this is correct, then you probably do not have a towing package, and if you did, it would not matter, since you are using the same power as the truck's lights use.
So look at it carefully again. If it's plugged into the wiring that the truck's rear lights in the bed use, and the lights in the bed do work, then there must be a problem with the connections at the plugs, or possibly someone has wired the large plug to a non-standard pin connection, so it did not match the u-haul plug wiring.

Does this plug ONLY control trailer brakes or does it also power the lights?

The big plug should have at least 6 or 7 prongs in it. And it will have everything in it, the lights, the brakes, etc. If it's the metal type, you can take it apart and you can see where the individual wires go, and they are labeled.
