Did you ever figure out the hyperflash?

Those look great on your truck. Definitely make the rear stand out. I have the same harness you got but am trying to find some taillights for a reasonable price.

Ok, still negotiating the purchase of my truck. I'll hit you up when I'm ready to buy the tail lights. I'm in the Dallas area.

Any luck on getting the hyper flash to stop? If so, what did you do to get it to stop.

Was told I need to get “box delete” programming from the dealer (basically turns off the hyperflash), but I just sent a email to WAMS see if they can tune my bcm to turn hyperflash off but haven’t gotten a response yet. (Hope WAMS can help) not trying to leave truck at the dealership for few days.

I wonder if another way of looking at this would be to have an updated cable harness that would include the appropriate resistors or maybe even return signal back to the BCM in order for the hyper flash to not even occur which would no longer require programming. 🤔

That’s above my technical knowledge 😂, but yeah that would be nice to have a resistor but I hate replacing them so I’d opp for the programming either way

Would these tail lights and harness work on a 2019 gmc at4 model? 

If u mean will they fit yes, will need conversion harness and the 2024 OEM LED 2500 truck harnesses (one for each taillight). Phil Gamboa had his hyperflash deleted on his truck and they work perfectly WAMS help him with his I believe (mine has a hyperflash still was told I had to have the dealer program mine but I haven’t taken it)IMG_5542.thumb.jpeg.faa630ee2e13b6cbfcd3614cc0d63dba.jpeg

So I got my custom harness (280$) for the taillight but I didn’t have the OEM harness for each taillight (ordered off ebay for 77$ for the pair) dealer wanted 125$ each harnesses 

 

custom harness below plugs to the body harness and OEM harnesses plug to the custom harness , the yellow goes to the power wire on trailer plugIMG_2428.thumb.jpeg.45f23b3ac7558f223ecbe225514c9fdc.jpeg

here’s the OEM taillight harness order 2 belowIMG_2434.thumb.png.2f890d3aab94074068aa03cdc9b36e11.png

I think @pgamboa was working on one, but I got mine from Gen5dyi til he gets his done

I got the hd taillights installed on my 2024 Silverado 1500 and got my harness from gen5 diy. Everything works except I had hyperflash and my turn signal didn’t work if I had my foot on the brake. I got it programmed at the dealer and the hyper flash went away but if one of the turn signals is on and I push the brake the opposite side starts flashing too as if the hazards are on. Once I let off the brake the turn signals work as they should. Could this be a problem with the gen5 diy harness? Has pgamboa made a harness yet?

I know they sell one on eBay that works perfectly but have run two wires to the bcm, I thinking ima swap mine with this one I’ve heard few people say they are good no programming needed

Have you swapped over to this one yet or gotten the program at the dealer. I got another harness built by gen 5 diy and it fixed my problem only thing is it’s doing the hyperflash when pushing the brakes only.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
