Easy swap but a pain to get the two longer screws back in correctly, glue issue was not a problem but did the swap on a warm day and the plug came loose fairly easily truck was sitting in the sun for a few hours which might have helped

I recently received my 2021 Trail Boss Custom and of course it has the “dumb” mirror. I went ahead and pulled down the console which only has OnStar and overhead lights, pretty basic. There are the 3 unused harnesses like others have mentioned. The dab of glue that holds the harness I need to upgrade my mirror is a little bit of a pain. I used a flathead screwdriver and sort of dug into the glue and just slowly wiggled and pried and it came up.

 

Now I know the harness is there I will order mirror with the garage door controller. Did anyone ever figure out what the other two harnesses are for?

This thread is so confusing.  It's about 2019-2021 trucks.  Why are guys outside of those years posting here rather than making a thread for their years and thus, cross contaminating the thread???

So I did this swap over the weekend.  I went with part number 13540312.

Got the harness freed pretty easily by using a hair dryer.

I did break the clips on the mirror cover insert so I had to order a new one of those.

I will say I haven't really notice the mirror working.  I've read others say it's not as noticeable as others, but I also haven't driven at night yet.  The closest I had was this morning when the sun was coming up.

I also have my windows tinted.

 

Anybody else have something similar?  Wondering if the mirror I got isn't good?

Thanks for the feedback.

I have the Gentex auto dimming mirror for sale. Had it in my 2021 Silverado. Works great, excellent condition. Plug and play, no wiring needed.

$100

Is there anyone that went to install the factory auto dim mirror and couldn't find the plug. I have a 2020 WT and I don't think it is there

Mine was super easy to find and connect to mirror.

Well WT models do not have harness with the plug for the auto dim mirror. Can anyone tell me the color code for the wires?

Black -

Red +

Green ?

Pink ?

Gray ?

Green is reverse trigger wire

Pink is auto dim outside mirror(unsure if left or right)

Gray is the other auto dim outside mirror(also unsure if left or right)

 

You really only need positive and ground. The reverse trigger just disables the dimming when you're backing up. It's only really an issue if you back out of a dark garage into bright sun, but I've had it on other vehicles with the auto dim on full time and it never bothered me.

Hey so I know I’m late to this party but I’ve been curious about the mirror swap thing too and adding vanity mirrors with a damn light. So after some research and reading through all 14 pages here while taking in the leg work some of y’all have done, it seems that there is only one wire harness for the headline and it seems it includes the the wire for the auto-dimming mirror and the vanity lighting it also seems that it includes adding the video rear view camera as well. Now who is brave enough to pull down the entire headliner to look for the connections??
 

 84711896 - that’s the GM part number for the headliner wire harness. 
13595368 - the actual GM auto dimming mirror.

13536995 - the GM auto dimming mirror that includes  video 

13532977 - the GM auto dimming morror with video and with the home link buttons on the bottom

For anyone thinking about performing the video mirror swap.  I have some excellent condition DRZ oem video mirrors and mirror kits for sale if anyone is interested. 380 shipped for mirror and 675 shipped for total kit (video mirror/harness/light/camera.  Delete if not allowed.  They are also listed on ebay for $400 and $750.  Ebay charges tax to customer and me then takes fees so I am trying to make it so we all win.

Has anyone tried this mod on a 22 refresh RST because I'm trading my 21 RST tomorrow?

 

I used the 13540312 mirror on my 21 and it has worked perfectly with the wiring harness in the head liner. From my initial once over the shroud around the mirror is much larger, I guess for the crash avoidance equipment. Just going to check here first before I order the same mirror.

I have the crash avoidance on my 21 Custom as part of the Safety Confidence package. I had to Dremel part of the bottom of the mirror mount because it interfered with the camera. It didn't take much and was able to put the plastic surrounds back on with no issues. The mirror I used was one from a truck with the towing package. I don't know what the part number is offhand. I found it on ebay for $45 and won the auction at that price.

If the mirror is a GM part look on the back (towards the windshield) driver side of the mirror there should be a part number.

    • The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge
    • Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).
    • The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.                 
    • It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.  
    • They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
