Thank's for the info!

I was underneath my truck draining my oil and noticed a missing bolt right off the transfer case. Anybody have a part number for it?

Gotcha... i have the 6.0L gas 2500hd as well. I am going to be running a front winch and occasionally a few other things. I'm waiting on the harness to arrive. Hopefully this simple set up gets me up and running. Thank you for your help on this!

One more follow up question....Does the set-up you described--with the GMC relay and harness--completely negate any 3rd party Aux battery kits? Do i need to buy any additional fuses or an isolator? Or are those parts you listed all I would need?

This is great info! Thank you

Ok, I think I understand what i need. Thank you for the picture. In the videos and pictures online it shows it like a typical ampmeter which encompasses the negative wires, though the examples I've seen online are either different year Silverado, or have been a 1500. I am thinking that for my model it is instead a 'plug and play' ampmeter through the harness rather than what i'm seeing as a circular enclosure that the negative wires feed through. Follow up question....with this harness do I still need an Isolator and fuses to add a 2nd battery?

I am installing a 2nd battery on my 2016 2500HD and just noticed I am missing an Amp Meter around the negative wiring. The harness is there, but the meter/plug is missing. I have no idea if this was removed by the previous owner or if it wasn't included during original purchase. Does anybody have a part number for the amp meter, or an idea if I can add one?

I'm replacing my old damaged tailgate (2016 2500HD) with a new one I ordered on ebay. Everything on the new one is identical except the right-sided tailgate hinge. The new one has a round welded piece (with a plastic removable cap inside). The truck bed has a rounded one as well. Is there a specific truck-bed bracket that needs to be installed?
