A few forum members have been lucky enough to pick up first generation Honda Insight hybrids at rock bottom prices because their hybrid batteries were "dead".

Kill Switch (EOC): Where did you install your activator? And what did you use?   Kill Switch (EOC): Where did you install your activator? And what did you use?
