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

I’m not sure what the person did that you asked, but I bought the kit from Pegasus above. His truck came with the kit, but not installed. When he shipped it to me it came with a new bolster that had the switch hole cut out. Unfortunately the new bolster was for a truck with push to start, which my truck does not have. I didn’t want to have a big empty hole in the panel where the push to start button would go so I used the measurements from that panel to cut the hole in my existing panel. Turned out perfect and looks factory. I would assume that they offer two different panels, one with push to start, and one without. 
 

If someone needs one I have the extra one with the the push to start option.

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)

Well the first picture is similar to the one in my truck. Just a different color. Well I added a 5 aux switch panel to it today. I didn’t want to cut into my dash just to add some switches. Plus I wan

Just finished the install, took about 9 hours going slow and figuring how it all comes apart. Mine was missing the red hardware bag and the battery stud kit  (bulletin#147) https://www.gmupfitter.com/files/media/photo/1143/UI Bulletin_147 Snow Plow power provisions_V2b.pdf  Probably when the dealer took it out of the back seat pre- delivery thinking it was left in there by mistake during assembly.

I wanted to clarify on your install for other people that have to do this. Did you install the VYU plow package wiring harness, and the upfitter  Switch harness? Is that what took 9 hours? 
 

The dealership is responsible for installing the VYU plow package wiring harness at no charge. That should be the bulk of the time, and the biggest pain. 
 

I installed the upfitter switches, and had maybe 1.5 hours total in it. Only had to run the wire from the fuses  on top of the battery to the switch panel inside the truck. Two screws to mount the upfitter fuse block, and plug a few things in.

I did not install the plow harness. I had to do everything else related to the upfitter bulletin. All my parts were loose in the back seat including a new knee bolster with the switches installed. The hardest part was removing the old knee bolster. The time was in taking care not to damage anything else and figuring how things came apart. If I had to do it again, maybe 2-3 hours.

Gotcha. So that was the same as I installed. I did give up on removing the bolster when I realized that the new one had the hole for push to start which I don’t have. So I ended up cutting my existing panel in place, which took about 10 minutes. It would be nice to see a breakdown of how the interior comes apart. From what it looked like (and you mentioned, most of the dash had to come apart to get to that. ? I liked the old trucks that you could have most of the dash apart in about 15 minutes.

Just had mine installed, they are nice!  Dealer had no clue how to install it what these were even for but I was able to walk them through it with the upfitter bulletin. Have a couple light bars and some other accessories plan on wiring in, nice to have factory switches!

I just received my 2020 AT4 with upfitter switches that I ordered from the factory. On the window sticker it says purchaser responsible for the install. When I asked the salesman if the dealership could install it he said he would ck. Long story short they installed it for me without making a big deal over it and didn't charge me for it. I bet if you would push your salesman you could get the dealership to install it for free. Also just a tip I didn't know about the switches can be set up to work when the ignition is on or off just by switching the fuse location.

Wondering where you found out about switching the fuse location to change switches to work with battery on or off?  Interested in this and couldn’t figure out how to do it. Thanks!

I didn’t try it on mine, as they were hot all the time, which is what I wanted. From the quick look I took while installing it because I heard that you have that option, I think you can move the 2 five amp fuses to the left (in your picture) 1/2 a fuse space. I think there are 3 contacts for each fuse. But that is just a guess.

I figured it out by looking at the wiring diagram. If you pull out the orange looking fuse and move it toward the relays and push it back in the relays will only energies when the ignition is on. One fuse is for sw 1 and 2 and one is for sw 3-5

My truck arrived with the switch mounted and no wires connected from the assembly line. 

Mounting the switches is the hardest/longest part. Is the little fuse panel for it mounted? Did you get a bag of parts?

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
