Sure. I think this is right.
The green highlight is the circuit for the brake light out sensor. If that is grounded, the warning stays off.
The orange highlight is the power to the brakelights. It goes though the brake light failure sensors, essentially each one has two internal relays that only operate if they see the correct (incandescent) current flowing through to each brake light bulb.
If all the brake lights are drawing the correct amount of current (the current used by an incandescent bulb that is not burned out), all four of the sensors close the circuit, and the green highlight path goes through each one of the four sensors (in series) and finally to ground.
LED bulbs use less current, so the brake light failure sensors don't see what they are expecting, and assume that a brake light bulb is burned out. Even replacing one normal bulb with an LED will trigger the alert, since the system is designed to monitor each brake light bulb individually.
To disable the brake light warning system, we connect the orange/white wire upstream of the brake light failure sensors directly to ground, so the system ALWAYS sees ground, so the warning will never go on. (Even if you remove all your brake light bulbs!)
