The Autowbrake electric break controller works from when the break lights get a signal volage right It seams like the voltage from the break lights stay the same so how does the Autowbreak system know how much pressure to use.

The Autowbrake Electric Brake Controller part # 3430001 is a proportional controller which means it applies the brakes in an amount, proportional to the force of how the brakes are applied in the vehicle. It uses an inertia sensor inside the controller that senses deceleration. The brake light circuit simply wakes the controller up and tells it to start reading the inertia and apply the brakes accordingly.
