On the 2.7 engine the electronic brake boost will stay on for 20 to 30 minutes after closing the doors. Also it will active anytime the doors are opened or locked with the key fob.
There is a great difference in the amount of brake pedal pressure required if the brake boost is off or on.

Well Ford just updated the towing TSB to 22-2360, here is the change:
"This article supersedes TSB 22-2210 to update the expected release date of the revised ABS module software.
The new software is expected to be available in December 2022."
Another clarification the electronic boost stays on for 20 to 30 minutes after the doors are closed then goes off. So it is impossible to set up a brake system because the required brake pedal pressure changes when the boost goes off.
This is what the TSB attempts to take care of.
This is what I posted a couple of weeks ago:
With the 2.7 engine and following the TSB (which will keep the boost off until the fuses are put back in) you will not have any electric brake boost.
Your brake system must supply enough brake pedal pressure without any boost to cause some braking...
That is the PROBLEM there is not any vacuum boost on the 2.7 engine. It is all electronic.

There are several more threads about this issue.
With the 2.7 engine and following the TSB (which will keep the boost off until the fuses are put back in) you will not have any electric brake boost.
Your brake system must supply enough brake pedal pressure without any boost to cause some braking action at the wheels.
Still do not know what the...
I only did it one time a long time ago. Straight back about 15 feet. Wife had her hand on the steering wheel through the window to keep the steering wheel straight and prevent it from spinning. It only take a second to really mess things up. It would be next to impossible to coordinate the...

Looking at these instruction pictures, page 6, it looks like they put them over the top of the frame and back down then connected them together.

There is a rubber plug on the drivers side for passing wires through the fire wall. Those are my brake system wires going through it. Just cut a slot and push the wires through.
Doing great, took a trip to Galveston a couple of weeks ago so grand daughter could swim in the gulf. Bronco do good, no issues. My super duper key fob presser still working great.
Just waiting to see what Ford is going to do. Hoping I do not have to go to a different brake system.
