• Q: How to replace the Fuse Box in the Body Wiring Harness Junction Block on 2009 GMC Savana 1500?

  A: One should begin replacement of the body wiring harness junction block by disconnecting the battery negative cable. The first step is to remove the driver seat followed by removal of the junction block cover. First disconnect the positive Battery Cable nut and then the positive Battery Cable from the junction block. Disconnect the electrical connectors from junction block only when yf7 equipment is installed. Liberate the junction block caged bolts completely and unlatch the tabs which secure the junction block to its base. First detach the junction block from the block base after unfastening its base nuts (1, 3). Lastly remove the wiring harness from the junction block base. To finish the process remove the junction block base which is situated on the floor. The wiring harness mounts first to the junction block base before you can install the junction block base on floor studs with caution to avoid blocking electrical connections (4, 5) beneath it. Screw in junction block base nuts onto the floor studs at 5 nm torque spec (44 lbs inch). Secure the junction block onto its base by seating all retaining tabs fully while bolt tension must reach 5 nm (44 lb in). Never omit connecting electrical connectors when using yf7 yet begin by attaching the positive Battery Cable to the junction block while installing its retaining nut and tightening it to 10 nm (88 lb in). After putting back the junction block cover, replace the driver seat followed by reattachment of the battery's negative cable.
