Location of the 40-Amp Fuse for the 2006 Chevrolet Silverado Tow Package

Question:

Im in the process on wiring the Prodigy P2 to my 2006 Silverado. Im confused about where the 40amp fuse goes that came with the factor wiring harness. Base on the owners manual under hood fuse diagram I believe it should go in the STD #2 position. However, there is a 30amp fuse in that position. Should I replace the 30amp with the 40amp that came from the factory?

The 40 amp fuse for your 2006 Chevrolet Silverado tow package is used for the 12 volt battery charge circuit. This fuse is located toward the front of the underhood fuse box closest to the front auxiliary positive post (see photo). There may be a dummy plug in the fuse slot. I have attached a video that shows where the 40 amp fuse is placed.
