Install on the negative post of your battery, attach battery cable to the switch and you're done! To engage power just hand tighten the green knob. To disconnect power, slightly loosen the knob or, on this top-post model, completely remove the knob to discourage unauthorized use while stored at home, parked, or when traveling.
