The extra red wire/connector that comes with the brake controller install harness part # 3023-P that you referenced connects to the brake pedal switch separately. This circuit is what tells the controller that you are applying the vehicle brakes and to start applying the trailer brakes.

I attached an install video for this harness for you to check out as well.
