I just finished mine, looks good.  Went with red opposed to black even though the truck is Onyx Black.  There's enough red on the truck as accents already that I didn't want to have to go and make everything black as it would have bothered me.

 

Just to give some bit of experience from my install:

  • Took me 60-90 min actually, which seems to be considerably longer than most here but still not bad. 
  • I spent a lot of time trying to route the wires and harness as best as possible to avoid seeing it through the grill.  Probably spent 20-30 min on that alone.  I did end up routing it similar to pictures from the 1st page incidentally.  Was difficult to squeeze through there but got it done.
  • Even after disengaging the clip on the headlight hardness, it was still very difficult to get it out.  Probably another 15-20 min here as well.  I don't know if my hands are bigger or something but it's just difficult to gain any sort of leverage.  I'm sure it would have been easier if you removed the headlight assembly per the instructions but even with the wasted time, I was happy not to have to remove the headlight assembly.
  • Taking the black cover off between/over the grill and radiator is essential to a successful install.  Removing the grill might have made things a bit easier, and I'm not sure it is very difficult to remove.  I saw 3-4 bolts but it looked fairly simple.  In hindsight, I probably should have removed it but it isn't required.
  • Saving the existing emblem is only possible if you remove the grill in my humble opinion.  Disengaging all the clips on the existing emblem seems very difficult to do without damaging them if the grill is still installed and the red inlays are still in.  Prying the red out of the chrome surround makes it easy but you will destroy the existing emblem this way.  No way around it.  I actually broke two small flat screwdrivers trying to pry out the red.  Tips of them snapped clean off.  They were cheaper screwdrivers but still, it's a tight fit.  Should have just went at it with a bigger screwdriver not caring about damaging them because they cannot be saved.

Overall impression:

  • They are not terribly noticeable in the daylight, which I like.  I haven't seen them in the dark yet but it's a good amount of light to not be obnoxious but still give it some pop.
  • Another user mentioned that the chrome surround is lost and that it looks better.  I agree.  The grill on my AT4 doesn't have much chrome really except the emblem.  It's a darker more subdued grey for the most part in other areas.  This makes the emblem fit better on the front end for sure, visually.  Unless you really like the chrome.  I know many other Sierras go full chrome in a lot of places (like the Denali) so if you like that look, you might think it's a small step back.  If you have an AT4 though, it's perfect, as they eliminated a lot of the chrome on that trim.

Mine is a 2019. The lighted emblem (GM Part # 84741557) works for both 2019 & 2020 year models. Personally confirmed. Yes, basically the harness has a dual ended pigtail... Unplug headlight

Just did the install. Took about 15-20 minutes. A few tips: 1. I would recommend routing the wire BEFORE installing the emblem. Would make plugging the pigtail into the emblem much easier! 2

Finally got around to installing mine. If you have active shutters it was impossible to get your hand back there to save the letters. Ended up breaking off all of mine. Took me 5 min to do it with breaking everything after 1 hour if trying to save everything ha...

Ordered mine from shopchevyparts.com (direct link below) last Thursday (1/30/20) and received it yesterday (2/4/20). Installing today. Will take photos and update when finished.

GM installation instructions are attached in PDF format. I suspect that grill removal and headlight removal will not be necessary....

Just ran across this today. Has anyone installed the new illuminated GMC emblem on their truck yet? I'd like to know how the install is and what it actually looks like in a truck. What's everyone's thoughts on them? I'm thinking of getting one but I'm kind of on the fence with it being too much. Part number is 84741557

I ordered one from ebay , should be here by Monday

Would it be possible for someone to post the measurements of this emblem please. Individual letters or entire assembly would be great. Want to see if it can work for 2017-2018. Wiring isn’t an issue just the size. Thanks

The dimensions for the T1 are “18 1/2" long and 3 1/4" wide”. The height is the same. K2 is 17” long

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
