Trailer brakes


Recommended Posts

Posted

I have a 2016 Silverado 1500

Im hooking up the trailer brake I decided to go with the factory switch which is located left side above the headlight. 4x4 switches 

The switch is # 84109447

i have the wire which came with the truck # 23184088 which has 4 wires  and plugs into the fuse panel     I purchased # 13576542 From Chevy which plugs into the switch and it has eight wires I cannot find any directions as to how to connect the wires in  which order. Does anybody have any information on this

Big harness just plugs into the on floor board connection center. But you need reprogramming for this to work or at least that is my understanding of it.

Thank you I do believe it is a dealer fix just checking to see if someone knew anything that I didn’t
Well that is phill gamboa. As he makes and sells the harness and knows of the programming or white audio. But last I read this was not a option at all. Hope I am incorrect on that.
Also just a note there are better trailer brakes that have nice small control knobs that you can buy a different trim panel and just mount it in. If this doesn't pan out.

ditto, if you search, is seems generally agreed on that you can't add the factory brake controller after the fact, you need to go aftermarket. 

 

If you find a way to make this work, you may be the first.

Just get a Prodigy 3 and a harness off of Amazon for a fast and easy plug and play setup.  One end of the harness plugs right into the firewall connector and the other end into the controller, so no need to use the factory harness.  And no programming needed.  Works right out of the box.  It took me about 15 minutes to install the entire setup in my 2016 LTZ.

The end result is... Even though our trucks have the plug in the dash for the factory trailer brakes, the answer is that you CANNOT add factory trailer brake  switch to a truck that did not come with it. There is a module under the truck by the spare tire that isnt there along with the harness for it. Many have asked this question. I mean it can be done if you had a donor truck and got the chassis harness and other stuff. But that's just crazy.

    • 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.  
    • Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
    • Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."    
    • Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.  
    • Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
