Seriously, the item on the left is is the underhood wiring harness from battery fuse block, 2nd is the fusebox for the switches mounted under dash going to a loose connector under dash and the switches, 3rd I'm not familiar with.

3rd might be for the snow plow prep package then. 
 

so 1 and 2 are for upfitter then?

Not sure I buy the theory of de-optioning a truck in order to get it built sooner. Unless a specific item is on constraint and noted on your order no one at the factory cares. Personally I think they

Mike ,  I have not tried these switches yet.  Do they have a positive "Click" when pushed in for "On", then Click again pushed for "Off" ?   If so, the latching could be In the switch and not an exter

I’ll label them so in another 18mo when I wonder again I’ll know lol. Do you think it would be that difficult to set it up I mean the 1-5 pad is already in the dash.

I did it with my 2020 HD AT4 and I thought the difficult part was getting the power wire through the nipple above the accelerator pedal.

 

 Since you don't have to worry about putting the switch pad in the dash the rest of the process is the same as the 2020-2023. 

 

This thread should get you there...

 

 

Good Luck!

I have a 22. So that should be the write up I’d use? Thanks

Yes. But you need to drop the knee bolster to install the fusebox for the switches. No idea why gm assembly line don't install them.

Okay I’ll have to set it up this spring. But then actually allocating things to those buttons has to be wired in directly from say button one and running say a light bar or something?

There are blunt cut wires on that harness that are controlled by the switches. You will just add your accessories to the wire.

 

You will only have 4 wires/buttons that are available. Unless you grap the green wire out of the gray connector that plugs into the loose connector under the dash.

 

That wire is for a roof light. It goes all the way under the headliner to the 3rd brake light housing. It is blunt **** along with a ground.

My spell check was off, I added a "n" to cut. Sorry.

Thank you for the great info. What stuff do you or anyone else power with the upfitters? I was thinking auxiliary lighting up and in the rear could come in handy

I use one switch to power a relay which supplies a ground to the bcm to put it into surveillance mode. This allows me to drop the tailgate and not scare game away with the dam turn signal lights blinking 3 times at 4am.

 

It's fine if gm wants to get all fancy and blink lights to warn people that something is going to happen when using the dash or fob buttons to drop the gate.

 

But jesus f***ing christ, there is absolutely no reason, if I'm pushing the tailgate button!

Yeah I’ve always thought that was completely unnecessary

Fellas, don't flame me but who has had a dealership install the package?  What was the cost?  I'm pretty handy but just don't feel like doing this.  Maybe it's old age or laziness.  But I am seriously considering having the stealership do the install - as long as it's under $400 dollars to do it.  I wonder what the book says for install time?

      GM Hard Folding Tonneau by REV review

      By cautious optimist · Posted

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
