It is for an aftermarket controller. When the truck was first sold they didnt have the harnesses available. They were having to alter past harnesses to make them work

I just receive a letter with a wiring harness in the mail...It states my truck has wiring provisions for an electric brake controller and the harnesses is part of the package but was not included with the truck .is this something that was supposed to be installed at the factory and is it incase I want to add a aftermarket controller?

I got the same thing this weekend. I think it's only a necessary wire if you want to install an electronic brake controller for trailer brakes. You should be fine to pull a trailer without brakes if you have a tow package.

Several people are getting these. Here is a thread on it already. http://www.gm-trucks.com/forums/topic/161289-did-gm-send-anyone-else-a-trailer-brake-wiring-harness-in-the-mail/page-2

Well after a week of debate/research, talking with the wife, driving my self crazy.. I bit the bullet and pulled off the Good Year LS2's (after the the vibration came back) amd put on some 305/50R20 Hancook Dynapro ATm's and holy cow... talk about smooth riding!!!! And evem more quiet than the Goodyears... should have never waited... they also make the rims/truck look way better... Guys I honestly think the Goodyears are just junk... so far it appears that my slight vibration/drone was solved by tires...

Was your vibration in the steering wheel or seats and at what speeds? Thanks!

It was a slight vibration could feel in steering wheel.. seat, and on accelerator, if you barely sat your foot on it... started at about 40 and would come with a slightly audible drone sound..

Interesting. Maybe it is my tires after all. If you don't mind, can you read from post #1603 and on from the vibration thread (link below) to see if what I and another poster are describing in our steering wheels matches what you are feeling?

Yep, that is my mantra here. Why spend 45K +/- and drive around on oems? Unless my ride comes with Michelins (most sporty cars have such) I switch the week of purchase and get some buy back on the oems from Discount tire. Choose the tire you like or have experience with and switch. I prefer Michelins. The Goodyear's for sure are a less than a good riding tire and poor wet handling.

I think its tires. .. and honestly thr goodyears are cheapo tires anyways. . 139ish... you wont regret buying hancooks, nittos, or toyos even if it doesn't fix your problem.

Had the recall done for the cold weather idle fire done. My fuel milage went from a

Average 20.5 to 13 mpg in the next 500 miles same roads, same trips, same me every day. 2000 miles later its came back up to 13.7 MPG. The dealer said yep that’s what happens when you do recalls…..Now there is another recall on something with the trans, They won’t do anymore I can’t afford for it to go down 7 more mpg.

The recall with the trans is inspecting the lines going into the trans. If you crawl under your truck on the drivers side the trans lines go into it on the side. You can see if it's leaking there or not. Their is no recalibration with this recall like with the fire one. It took my dealer about 5 minutes to complete.

Yup, just a visual inspection. Possibility a wrench maybe involved as well. That's about it.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      The Peckish Synapse

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
