Changes to wire schematic for brake lights on 2025 6g's?

[BluebroncoNC]

Trying to wire up a hitch mounted light/brake light/running light and I'm hearing from the manufacturer; something has changed in Ford's brake light wiring for the 2025 Bronco. Their jumper is not working as intended, "turning off the trailer detected" issue with their bi pass. Suggesting I try the third break light wiring at the tail gate to find a "clean" break light power source.

Anyone else dealt with this?

The wiring is the same, I think the wire colors might have changed, but the pinouts are the same.

The electronics that control the wiring is different.

Ford has altered for 2025 the method by which it detects brake lights, apparently. Ordered a hitch mount light kit, back up, running, brake light from Diode Dynamics. At plug in, the "power feed bypass" to either brake light assembly harness or the third high brake light assembly still gives a "Trailer in tow" warning, whereby shutting off proximity warnings in the rear. Which would be fine if I was actually towing a trailer, but not so much when I have the light installed. Diode has issued me a refund and shipping label until such time as they can figure out a fix.
