Connect a Vehicle Memory Saver

What happens here

This step introduces the solution: using a specialized tool, often referred to as a vehicle memory saver or power maintainer. The video implies the use of such a device, specifically mentioning that when the negative battery cable was disconnected, power was never lost to the vehicle. To achieve this, the memory saver tool is typically connected to an external 12-volt power source (e.g., a separate 12V battery, a portable jump starter, or a wall outlet adapter) and then to the vehicle's electrical system, often via the OBD-II diagnostic port or directly to the battery terminals (before the main battery is fully removed). This creates a temporary, continuous power supply to the vehicle's essential electronic components.

Goal: Provide continuous power to the vehicle's systems before disconnecting the main battery.
