Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I am installing a new hydroboost system an it requires me to disable the ignition system and still crank the engine. I would normally disconnect the battery cables to do this but it wont crank without power. Any suggestions

Look in owners guide for inertia, or fuel cut off, switch (right kick panel maybe) tap it to trip and shut off fuel, when finished push button to reset.
