Yes. I'll get that pic this morning and post it shortly.

Ok, here you go. This is extended.

Looks great.  Thanks for posting all this information.   It will help a lot that want to change out to these. 

 

One thing that makes me mad is that they don't power fold.  I couldn't get into my garage without folding them and having to do that manually every day would get old.  Power extend isn't needed but folding for me is kind of a must.

 

What is the other harness you talked about supposed to do?  Also I was told that our 2019 harness would not plug into these mirrors but looks like I was told wrong.

You're welcome.

 

So regarding our existing harnesses plugging in, yes they do. Identical plug and play. However the factory harness does not have all the circuits for all the mirror features. That's where the replacement harnesses come in. Depending on what model you have, there are several part numbers GM has put out. They don't seem to be available though since I spent all day Friday calling around and the numbers exist, but are not available to order.

 

Yes, it does suck they don't power fold. However, as time goes on, we should be able to find part numbers for mirrors that do. The mirrors I bought are on the GM Accessories site, and are pretty basic. However, you can spec a new 2020 with an LTZ or High Country trim w/Tow Mirrors and it says it can have power fold, 360 vision, etc. So they do exist. They also have chrome caps on the higher trims as well.

 

On a side note, these mirrors fold much easier, yet still have all the tensile strength as the K2 Tow Mirrors did. When you push to fold them, the mirror makes an upward then backwards movement and folds pretty close to the truck.


I'm sure all the options will come available soon enough.

New here but I did find this on Boostautoparts 

site

Planning to order these in the next couple days. 
 

is this harnesses your have listed that are needed? I came across this list too.

Welcome and thank you!


So the first link you posted is actually a modification for trucks that came with either puddle lamps or tow mirrors from factory. That adapter fuses together two circuits and allows those lights to come on when you backup or when you unlock your truck or turn on the cargo lamps. It does not help if you did not have puddle lamps or tow mirrors from the factory.

 

The second link is indeed what I need. However I finally got a hold of the right person at GM yesterday - these parts are not available yet. No location in the entire country has them yet because they aren't being manufactured. Well actually that's not totally true - the assembly plants have them for the 2020's they are currently building, but they are not yet available in the parts department.

Thanks man. Yeah so I don't know why I said that. I "assumed" and sure enough - made an ass of myself. I'm thinking there are NOT turn signals in these mirrors. I see no opaque dots in the glass of the mirrors. GM probably did not put it on the tow mirrors either.

 

When I test drove my 2020 2500HD I was also surprised they didn't have the turn signal arrows in the mirror glass anymore. My dealer told me it was probably too bright and a distraction for the driver at night. So we tested the new mirrors and you can see the amber turn signal on the mirror's outside edge from behind the truck, but not from the driver's seat.

First of all - beautiful truck. I am supper jelly.


Second - wait so are you saying your amber lights flash as turn signals on the new mirrors?

Notice any increase in wind noise from your new dumbo ears?

Noise - no. None whatsoever.

Thank you. It has been a great truck so far.

 

Yes the mirror amber lights flash as turn signals. They also have the white LED "work lights" that shine out the front.

I picked up a new 2020 AT4 on Friday, it has the trailering mirrors, they are chrome capped.  From what I was reading I wasn't sure what power features they had.   I'm happy to report they power in and also power out with a button by the mirror controls.  They mirrors move in tandem, so both either close in or power out together.

 

I was worried that the mirrors would be too big, but they fit the truck nicely aesthetically / size wise.  They are a little big (blocking view)  when driving in more congested areas like parking lots or 4 way stops, but that is something I think will be fine once I get used to it.

Hey Steve. Thanks for that info. Yeah I agree they do block the view a little bit. You definitely have to be more careful than normal at 4 way stops.

 

And yes, your info confirms what I thought. Do you also have 360 surround camera on your AT4?

Yes, it has the 360 degree surround cameras and there are cameras built into the base of the mirror mount.  There are two white LED lights built into the outboard side of the mirrors, these shine to the rear  when you activate the switch that lights up the box (includes outside mirror lights, two rear corner box lights and the white lights on the back of the cab that are on both sides of the high brake light.)

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