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

Thanks!

I did most of the install.

I bought the new knee bolster but decided to use it to make a template and just cut the hole for the switch.

I ran the wire across the engine compartment and through the grommet.

I didn’t get started until 5:30 and ran out of light.

Tomorrow I will find the end of the wire under the dash, put it in the plug and then connect the battery end.

It took me around two hours so far... The last 1/2 hour was spent searching for the power wire in the driver’s knee well. I should have given up and waited for daylight.

It will also probably help to have a second person move the power wire while you’re under the dash so you can see it easier.

I’m going to hook up a ham radio, an air compressor and eventually some extra lights.

Nice work! The hardest part is definitely installing the new knee bolster as the whole dash has to come apart so good call drilling a hole in your current bolster!  Have a few lights hooked up to mine so far, probably going to add some more with a back rack!

Does the 5th switch always have to be used for snow plow prep? I would like these for adding some auxiliary lighting. I don’t have any need for a snow plow so it would be nice to use that switch for something else.

No just have to find the wire that feeds the beacon

I purchased a 2020 2500 Denali about 2 months ago. I'm not sure if it's because I live in Canada but there was no option for upfitters switches. I didn't know they where available until I found this thread. For reference I have the snow plow prep package and 5th wheel prep.

Did you custom order it from the factory? It should be available for U.S. and Canadian markets. 

 

If you "build" a truck on the Chevrolet website you should see it listed as an option to select.

      Cold start Miss, oil in cylinder

      By Keith179 · Posted

      I’m out of ideas on this truck. 2020 Silverado 1500. 5.3 135,000 miles. Has a p0308 and p050d codes. Smokes From exhaust when cold. Compression test passed. New plugs, wires and coil on cyl 8. Same issue. New coil on 8, no change. Replaced injectors, no change. Bore scope showed oil pooled on the piston after sitting overnight. Pulled head and had machine shop check it out. No cracks. Stem seals looked good, replaced anyways. He also ground valve seats. Put it all back together and still have the same issue. Bore scope shows oil on the piston again. Leaning towards maybe a cracked ring but unsure. Cylinder looked good when the head was off, no scoring or scratches. Any ideas on what else I should look for?  Appreciate the help

      2021 Silverado 2.7L – N232395310 – Can someone with GM dealer access check my VIN?

      By HeronLeal · Posted

      Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you

      Tire psi

      By jgaudet99 · Posted

      Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.

      Tire psi

      By Chuck FB · Posted

      Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight.

      Tire psi

      By jgaudet99 · Posted

      Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.
