We don't have the install wiring colors of the brake controller install wiring for your 2019 Ford F-750 but what we can help you determine which wire to use for the red wire of the brake controller. What you'll need is a circuit tester like part # PTW2993 and you'll want to test all of the wires leading to the brake pedal switch till you find a circuit that has voltage only when the brakes are applied. That will be the circuit to use for the red wire.

I also attached a link to a page on hardwiring in brake controller installs as well.
