Hello guys,

As i am not a fan of cutting the original wires and adding resistors and so, i was thinking maybe there is a certain harness that replaces the orignal one ? So that leds wont have a hyperflash

 

Will the slt harness work fine or what ?

If there is any idea that doesnt include cutting and adding resistors please help me to it

Check out the last few pages of this thread. A harness has been made that makes the 2016+ LED tail lights plug and play with resistors on the 2014+ GMC Sierra.

 

Zmnypit is working on making tail light harnesses. Best bet is to send him a message.

The hyperflash is how you are alerted of a "bulb outage" and is based on the power draw. Since LED draw less power than the stock incandescents, the only way to correct that is with resistors. This is controlled by the BCM and no harness without resistors will fix that.

 

You can - get your BCM custom flashed by GTPrix to have the LTZ/SLT "profile" to correct this, but there will be a cost for that and some downtime as you would have to send your BCM in for the flash. It basically changes the BCM's logic in knowing you have have LED lights and therefore seeing the lower power draw as "normal"

 

I have upgraded both head lights and tail lights on my 2016 LT Silverado and tried many times. Resistors are the only way. Gen5DIY makes a Plug and Play Harness with the resistors inline so there is no cutting/splicing into your factory harnesses. Check them out online.

I saw the Gen5DIY but it so damn expensive

What about a flasher relay ? Is there a specific good quality one ?

If i had to go with the resistors, do u recommend a specific brand ?

I said the same thing about the pricing. I have actually sourced out the connectors, pins, wiring, resistors and tools. When you add all that up and the time it'll take to crimp it all, their pricing is not that far off.

 

Just in materials, it was about $30 or so. Crimp tool is about $25.

 

I think they have their PnP harness (for 2016) for like $79.99.

 

I don't have any info on a flasher relay. Want it as Factory as I possible.

 

Resistors are 50W 6 ohm - you only need 1 for each side (unless you are 2014-2015) and think you'll need (1) for each turn signal. - CUTEQUEEN TRADING 4pcs 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights or DRL (Fix Hyper Flash, Warning Cancellor) https://www.amazon.com/dp/B00DCULNXS/ref=cm_sw_r_cp_apip_DWIjGcZje4Zmn

I went from Factory Stock LT to Factory Stock LTZ. For both tails and Headlights.

Is it possible to revert from LED to non-LED tails? My original LED tails are full of water and they are just very much overpriced to replace. If I can revert to the non-LED option, I can put some tails worth giving so much money for (e.g., Morimoto XB).

 

Thank you!

      I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there.

      Anyone have a spare?

      Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks

      Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.

      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.
