Good catch, I missed his sig when I commented. This will NOT work with an automatic since the ecu detects the brake signal and restricts the throttle. Its the same issue you run into when you try and brake boost (for the boosted guys). You have to disable the electronic throttle control completely (and lose your cruise control) or tap the wire running to the ecu that sends the brake signal.. and lose your brake lights. Not 100% sure tho, I did a bunch of research on it a while back but gave up once I realized just how smart the ECU is and how much work it would be to trick it into letting me do it
