My AT4 didn’t have the option so I ordered the parts and installed it.

All the parts were $287.58 including tax and shipping.

I did not install the knee bolster, I just used it as a template and cut a hole in the existing one with a utility knife.

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

Here is a notice on https://www.gmupfitter.com/ that came up immediately when I accessed the website.

 

 

UPDATES AND NEW INFORMATION
Upfitter Switch (9L7) Service Parts Retrofit Kits

It has recently discovered that there is a problem with the list of contents for the Upfitter SERVICE PARTS retrofit switch “kits” for vehicles that were not ordered or built with the 9L7 option. The discrepancy has been corrected and new part numbers are being generated.  The kits are temporarily on “hold” until they can be properly assembled with all the components required to perform the retrofit.  Stay tune for updates coming soon.  This situation does impact the kits that are shipped with the vehicle when the 9L7 option was ordered.

 

NEWLY RELEASED BULLETINS:

161 - Next Generation Body Style Snowplow Jumper Harness Install
165 - Fuel Filler Elbow Assembly `Service Body’ Installation MD
164 - Overhead Auxiliary (Upfitter) Switches (RPO UEH)
163 - Fuel Tank strategy and Auxiliary Tap Upfit interface MD
162 - Rear Chassis Electrical Harness Attachments – 3500 Chassis Cabs

VEHICLE SPEC. INFO.


Upfitters looking for various model option information, vehicle weights (both curb and available payload) should use the Online Order Guide accessible from Resource page of the GM Fleet website. Select the vehicle application and Click on `Model and Option Weights' located in the lower left corner on specific model pages. (https://www.gmfleet.com/guides)

 

I'm not sure how old the notice is as there was no date attached to it.

Here are the part numbers I ordered 12/28/2019.

The numbers could have changed but these were all the parts necessary to make the switches work.

84497098 Harness $86.95
84524205 Battery cable $39.01
84669070 F Block kit $38.05
84688687 Multi Switch $20.07
84487354 Knee Bolster $44.86 (this was black).

Hope these numbers are still valid...

So you already have the factory upfitter switches but are looking for more? Or where are your current switches?

If you don’t have the factory upfitters then the part numbers are posted above your post and you could order that and install them.

Sorry if I’m misunderstanding your post too :)

Post #79 in this thread has a picture of the upfitter switches (they mount in the knee bolster to the left of the steering wheel).

Post #94 has the part numbers I used in Late December). They arrived in the middle of February.

Thank you for all the replys , no there was no factory spare Auxiliary I will try to ordering new knee bolster  using those numbers u mentioned in February thanks as for the light bar mount it was a bit of cutting to get 20" in and I had to fab brackets because lack of room angle of feet .

it does sit in front of bottom luvers I would recommend a smaller bar.  Note: luvers must be working or causes a engine light found that out the hard way.  ( would not recommend blocking air if your a regular heavy hauler.)

Thanks again

My dealer said the same about my 2019 but these aux switches will go on any T1 truck. They just don’t want to do it or be responsible for it.

Those fit on my 2020 AT4 HD2500

It’s confusing but I saw the same message.

The upfitter switch plugged into the factory harness, the fuses fit exactly as they were supposed to, the knee panel looks like the perfect match.

I confess I did not use the knee bolster panel. I just measured where it should be, made a cardboard template and cut a hole in the existing knee bolster with a utility knife.

I zip tied the auxiliary fuse box to the mounting holes and saved a bunch of time since the process for taking off the knee bolster is time consuming.

Everything works as described....

I won't need the knee bolster as I'm gonna extend the wires and put the switches up in the headliner

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
