I have just installed the optional chevy brake controller #22822675. It took about 20 min. to install it. There were no instructions with it (normal). There was a harness with plug at the rear of the original light panel that was taped off. I found that it matched the receptacle on the rear of the brake controller and the colors of the wires were the same as the harness for an aftermarket controller. I do not have my trailer available to see if it works. Nothing happens in the information center. Is there something else that needs to be connected?

I was unaware GM actually offered their own add on trailer brake controller....What is the actually brand?

 

EDIT : I misunderstood the OP. Thought he was saying GM had their own aftermarket controller that could be ordered.

That part number comes up as the whole left-side panel with the controller's...um..controls. My understanding, per threads in this forum and what I was told when I ordered the truck, is it isn't "plug and play" if I wanted to add it later. While it can plug in, there's other stuff needed, including a different computer flash to support it.

You need to run, not walk from your dealer as they are clueless. As just stated GM sent out a bulletin on this very issue right after the 2014 (K2xx) trucks came out, if the truck did not come with the factory trailer brake controller it CANT be added after the fact. There is no way to add the dash controller you are talking about into the truck or program it to work.

 

GM will supply the pigtail harness that will allow you to run an aftermarket brake controller, you need to speak to the dealer or the parts department in order to get the pigtail.

Sorry, I guess I wasn't clear in my response. When I went to order my truck, I asked if I could add the controller in later if I needed it. They said no, it wasn't something you just dropped in, as there was all kinds of parts that part of the system, including different software. So I sprung for the $230 right then in case I needed it. That, and I didn't want a blank area. I like buttons.

If what you're saying is that you purchased the panel with the switch, you wasted your money so I hope it didn't cost much.

 

Unless you're truck came with the GM brake controller out of the assembly plant, the only way to get trailer brakes is to buy an aftermarket controller.

The GM integrated brake control is only an option on the build sheet, it can not be added to a truck after the fact.

 

The part you bought is for the switch assembly only, it will not make you have trailer brakes.

I forsee that truck being sold used to a buyer that thinks it has the integrated trailer brake....only to later find out the hard way that it doesnt..... better check RPO codes when buying used....

 

I do appreciate that you are trying this. Maybe computer reflash next? I eventually added cruise to my 07 when it was thought it could not be done....

OP I'd take that out because it is useless without any of the correct modules. Trailer brake module is not there, relay, and I think the BCM is different. A big ??? if the wiring for the trailer brake module is even in the chassis harness, if not, then the chassis harness is different.

 

GM says a big fat NO to installing a factory brake controller. Trucks not built with it, you have to find your choice of aftermarket brake controller and use the supplied blunt cut harness that plugs in. GM does offer a controller made by Curt as well.

Walt, did this ever work out for you? I am dealing with an identical issue.  I have a 2014 GMC Sierra that did not come with an integrated brake control assembly at the left side of the steering wheel column. BUT, I do have the 7 prong trailer connector at the bumper with the tow package. I've been towing without brakes with my horse trailer just around town.  I removed the panel and there is a wire harness/plug. I purchased the new control assembly 22822675 (Picture attached) but now I need to find out about the update for the Intellilink software to recognize the trailer gain control option and view.  There is not option to add it in the Settings/Info area.  Called GMC and ACDelco with no luck.

Any advise/thoughts/input would be greatly appreciated.

Never gonna work per GM bulletin.

If it's never intended to work, howcome when I removed the old panel, there was a wire harness/plug ready to plug in?  There must be a way to use this.  Help?

Hi, I see the harness plug there when I removed the panel, I too purchased the ACDelco 22822675 part and of course it doesn't work.  UGH!!  Do you have any recommendations for what aftermarket part will work best with this?

When I hit the trailer brake lock up it comes across the DIC and shows the gain output so it’s def tied into something program wise somewhere.

You need to program your body control module, and probably add all harnesses required for it. I too added the oem TBS on a new dashboard trim and nothing happen, honestly I wasn’t surprised I just hated the cubby it only collected trash and dirt., I tap the + and - from my headlight switch control to illuminate at the same time as all my automated night dashboard lights. It worth for me cosmetically, as far as functional there’s a lot involve that I don’t think is worth it for me since I don’t tow that kind of trailers other than a 12x6 enclosed trailer and. 10x6 utility trailer for my remodeling business. Beside my 5.3 has enough towing and handling power. Personal opinion.

      I wonder how much carbon is on all those high mileage valves?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
