Well, I guess I learned something new. Did not know that. I thought the brake buddy simply got it's signal from a motion sensor that would signal the compressor to apply pedal. Is it a certain modal Brake buddy that does this? And, how does it get wired to sense when the brakes are being applied?
When you press your brakes your brake lights turn on even if ignition is off. That's how my tj is wired so assume others are the same. Brake buddy simply presses pedal. That would turn on your brake lights regardless.
