When jump-starting a vehicle, which connection should be made last?

The last step in a safe jump-start is to attach the negative booster cable to a grounded metal surface on the vehicle being boosted (typically the engine block) away from the battery. This provides a solid ground and keeps sparks away from the battery, where flammable gases may be present. That’s why the final connection is the negative cable to the boosted vehicle’s engine.
