I ordered the 7 way to 12v socket adapter.  Will try that out and report back.  I know it doesn't work on the newer Fords with the smart plugs back there.  The new GMs are also smart somehow as in they know when a trailer is attached.

The bumper 7-way has a live 12 volt circuit. I rigged up 3 of these for my trucks to backfeed a battery maintainer during the winter months when 1 or 2 might set for a month at a time.

zero interest in a CD player here.  Had one on my 2016 and never used it once.   But I used the 12v power outlet for my RV camera system a few times a month.  We leave on a 4000 mile trip ne

Put the 7 Way with 12v. Cigar lighter on the bumper 7 Way for a few hours, with cell phone charger. Power did NOT time out.  Also turned on bed lights from dash switch. Timed out after about 10 min.

Great idea for an easier battery maintainer hookup.  Had  heck of a time getting to the Neg. Ground stud behind battery at firewall, to hook up my maintainer cable.

I ran my maintainer wire right to the nut on the neg top post. Been working fine.

I have a 7 way to Cigar socket adapter I saved for my new '24 HD, did not put on my temp '18 1500. Going to do it as a test, to see if the 7 Way still has the 12v. with the Ign. key OFF.

Perhaps newer GM's "time out" as a battery saver.

I did NOT know until today, ALL the 12v. cabin outlets are deleted  !! I saw the GM 1-'22 bulletin posted here. This is really a bunch of "Horse & Cow Pies".  Really ???

FN rediculous. Now I'll have to hide a dual socket cigar lighter in the Denali console somewhere, and another in the console area facing the rear seat.

 

The truck always has been my mobile office. Always have things charging.  New '23-'24  Re-located cell phone charger under center armrest is better, but cannot see it. More distracted driving ?

I made a metal bracket to wedge between the console upper  intersection to the lower dash for my '16 then '18, for the phone suction cup / charger. In plain sight all the time.

Will not work with the re-fresh dash design.

Option.....a Weathertech Cup Holder Cell phone mount, or I'll design and make my own again.

 

Love the style of the new design dash, but now finding it's limitations.  The elimination of 12v. ports has my blood boiling, for a $$$$ truck.

That's what prompted me to start this thread too!  These trucks are supposed to be utility platforms.  Why remove a utility feature that's so frequently used by guys who actually use their trucks?  If they wanted to save $, I'd rather they cut down on the amount of useless sheet metal they put on these things to make them obnoxiously oversized.  I'm 6'5" and have a hard time reaching things in the bed or under the hood that I shouldn't have issues with...

 

Only other comment I'd make, on the distracted driving thing, if you're like me and use Android Auto, there's zero reason to ever look at a phone screen while driving.  The new screens especially make this the case.  I like the wireless charging where I can't see my phone.

I KNEW I HAD YEARS AGO,  A MALE CIGAR LIGHTER PLUG TO A 12v. "BINDING POST" & "BANANA PLUG" ADAPTER.

WHERE YOU CAN SLIP WIRE UNDER THE POST AND SCREW DOWN, OR USE A BANANA PLUG USED IN THE ELECTRONICS AND MUSIC INDUSTRY, TI INSERT IN THE END.

MY SEARCH FROM ALL RV AND TOWING SUPPLIERS AND MFG'S N/G.  THEN REMEMBERED I PURCHASE A LOT OF STUFF FROM JAN ELECTRONINCS, THAT SUPPLIES THE LOCAL PFIZER PHARMACEUTICAL AND GENERAL DYNAMICS / ELECTRIC BOAT FACILITY BUILDING OUR NAVY SUBS.

FOUND IT !!  MADE BY PHILMORE / LG CORP.  P/N 48521.

 

FYI JUST GOT A TWO POST 12v.  CIGAR LIGHTER RECPT. FROM O'REILLYS, TO MOUNT INSIDE MY '24 HD ARM REST CONSOLE BOX, WHEN TRUCK ARRIVES. 

JUST LOOKED A '24 GMC AT4X TODAY, THE 115v. RECPT. IS INSIDE THE CONSOLE ARM REST BOX NOW.

Thanks  !!  Point well taken on phone app. and Android Auto.  At my dealer yesterday, they have a '24 AT4X, I got the keys and got her running to see the  Android app first hand with my phone in the charger armrest. Yes very handy. But Could not get my Weather Channel app to display on that screen so far in this quick evaluation. I travel extensively for work, so will try to get that app on the GM screen after I have my truck. My '24 said is now loaded on a rail car in Flint, bound for a Jersey dispatch yard. Yea !!

 

Suggestion for bed access for tools etc. Attaching a pic of my '16 HD , with a "Cargo Glide" slide out. Got  this for my bad knees, to not crawl into the bed for tools etc. 2016 GMC 2500-HD PULASKI AT SHOP OIL CHANGE.pdf2016 GMC 2500-HD PULASKI AT SHOP OIL CHANGE.pdfSeveral different brands out there, and also ones with weather-tite compartments, for those with no cap or tonneau . PDF pic for the slide out is named '16 oil change at shop.

Here is a better pic of the Bed Slide out I got in '16. Transfer to my '24 very soon.  These come in Aluminum or steel. Full or partial extension, and weight capacity. This one steel, full extension, and 2500 lb. capacity.

Ordered the 7-way to dual 12v plug and happy to report it works with the ignition off.  This will satisfy the 12v inflator use case.  Doesn't solve for those needing higher-amp 12v in the cab but it's better than nothing.

Adding 12v. in the Cab,  fairly  easy, Fuse "Add-A-Circuits",  from "Littllefuse" and Bussmann".  Napa should have these as well. Most of these fuses in the left & right Dash are the "Micro" not "Mini" size.

 

To go the Full Monty.....the 9L7 Upfitter Dash kit is still not available , for the '23/'24  "re-freshed" dash design.  This gives the 5 Aux. switches, wire harnesses, fuse block, and dash panel with the cut out for switch block assy.

 

One dealer build & price site, the '24 HD can be factory ordered with the 9L7 option, but is blocked out for Denali etc.

I'll add this GM Upfitter Bulletin #153e, dated 6-2-23 FYI. Has the kit #'s. I ordered the GM kit # 84942074, says for push button Ignition. Molded dash lower pad is  still for Pre-Refresh dash design.

Also Upfitter Bulletin #153p, dated 6-26-23, regarding Rearview Camera, for those that tow & have a cap or camper on the bed, info may help. Will have to send in another post. Think I'm at the file size limit.

I know it’s an older post but put together a 7 way trailer plug for charging. I have two Battery Tender Jr’s and one Battery Tender Plus. I only ever use two of them at a time and used the ring lug connections. 
 

I took one of the three alligator clamps that I wasn’t using and cut it below the fuse holder. Used a Hopkins 7 way trailer plug from WW. Put it together and works good with my 2018 1500 with 2 of the maintainers. Don’t have a pic but looks like the one gemarsh posted.

 

Will work on getting a 12v outlet in the cab whenever my AT4 HD arrives.

 

Edit: Added pics.

One more pic with a charger shelf behind the truck. Cords are wrapped around the back of the post. Truck was last driven yesterday morning, took about 2 hours for full charge.

      Tire psi

      By jgaudet99 · Posted

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?

      Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date.

      And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access.

      Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.

      AUX switch install

      By SwitchBladeSierra · Posted

      Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.
