Really the knee bolster was the hardest part to install. The rest is fairly easy, plug in, hang the fuse block and run the wire to the battery. I went to the dealer to get the missing battery stud kit today. There are 12 in California, may be awhile with the holidays.

I have this connector hanging next to the BCM. Is this where the upfitter switches would plug into? I know you had to install the whole harness, but maybe mine is already installed??

The dealer did install a big bag of parts in the back seat that included studs and fuses. It was UI bulletin #147 that covers VYU plow package and 9L7 upfitter switch power provision.

Where are the RPO codes listed? They are not in the glovebox like I am used to.

Yes, that appears to be the connection location, mine did have that there installed. If you push in on the tab on the left side, that cap will come off and then you plug in the harness with the new fuse block that hangs under the column. The bulletin # 147 kit is what I am missing to connect to the right side battery. This is all on top of the battery, below the cover.

Not sure on the codes, should say in the manual.

I misspoke earlier, I have the studs and fuses (147) that the dealer did not install, but told me I need to. They did install #124 which was a whole wad of wires. Is that the one that you had to install?

No, #124 is snowplow prep related. It has something to do with large electrical loads and the infotainment/radio performance. Dealer is supposed to install that if requested. #153 is Upfitter switches.

My buddy has one of these trucks he just picked up on Tuesday. He has snow plow prep but doesn't have upfitter switches. Anyone know how you're supposed to switch the strobe in that case?

I am going to do more investigating when I get home next week and back to the truck. I might just mount a single switch where the upfitter switches would mount. I am running a Game Changer strobe setup that plugs into the BCM right there anyway, so I just need to get a power wire to that area for the switch. Right now I just wired a cigarette lighter end on it to test them out. The video I have of them is to large to upload, I will have to try to get a shorter one later. It uses all of the trucks lights as strobes instead of having to mount a strobe light on the truck.

I have an upfitter kit that came with new 2020 Silverado 2500HD truck. I would be willing to part with it as I don't ever plan on putting a plow on it.

I think I would throw the switches and the keys over to the sales manager desk, keep you $70,000 truck you can't install ordered parts on. Truly unbelievable.

I guess is it the plow harness, or the up fitter switches?

So im in the process of ordering my truck and trying to get all the info on everything that im gonna need to get it built when I receive it

few questions

1 what is the amp rating on each switch. it says there are 3 30 amp and 2 20 amp I don't think I will exceed any of those but want to know before I layout what they will activate.

2 is the roof beacon wire already predetermined in the switch layout. I plan to run a 'roofbeacon' but also some other cornering lights.

3 some of the bulletins posted here are for the 1500 are they the same for the 2500

any help would be great

pictures/videos would be better to help everyone thru this

thanks

Looking at the wiring schematic it looks like switch 5 is dedicated to the roof beacon. The others are user configurable. Attached are the installation instructions.

So if I'm reading that right the switches go

30 20 20 30 30

The fifth switch is the roof beacon
but can i tap into that wire under the dash to re route power out of the firewall

They do light up too, the 4 blunt cuts out the bottom are for your connection. #5 is the roof beacon wire that is coiled near the 3rd brake light. (snowplow prep pkg)

did you have to cut the hole? Or was the switch mounted and you had to run the wires?
