How to replace the Fuse Box in the Body Wiring Harness Junction Block on GMC Savana 3500?

Disconnection of the battery negative cable starts the process of body wiring harness Fuse Box replacement followed by removal of driver seat installation. The procedure requires removing the Fuse Box cover followed by unfastening the positive Battery Cable nut and positive cable from the Fuse Box.
