I just wanted to thank Phil for being the real MVP on this topic! I wish I researched a little more before I trusted the dealer. (It would have saved about a months worth of hassle and time). He confirmed part numbers and was a big help in the harnesses. I put factory DQS mirrors on my 2016 Silverado LTZ Midnight.

Welcome!  Yes, Phil is great!   And your avatar is awesome by the way!

All,   Due to the overwhelming interest in folks wanting to upgrade their mirrors, I wanted to start this thread, hopefully, with all the information pertaining to the process of upgrading y

For those that are curious on the work involved with the harness modification, I've created and uploaded a Time Lapse Video of the process. The original post has been updated and the video link is at

I was told that 1A Auto has replacement glass. Have you tried to contact them?

Getting ready to upgrade my 2016 Chevrolet 2500 LTZ Diesel from DL3 to DQS.  Someone make me an offer on my DL3 mirrors so I don't have to look at them sitting on a shelf for the next 5 years.

Upgrading my 2017 need the harness for folding option everything else is working

I answer most all questions on the first post of this thread. There are many different mirrors out. Each hanress I build is specific to year, trim, and mirror you have now and mirror you want to upgrade to.

I installed  Scitoo tow mirrors on a 2016 2500HD LT. I also had to upgrade the harnesses for the doors as well to get everything to work. Everything is now working but when the lights are on the blinker lights come on as well, then when the blinkers are activated the mirrors do not flash and the pickup light have a hyper flash issue. Does anyone know what could possibly be wrong?

This is MOST likely because the manufacture of these mirrors have the running Lamp (Amber forward facing light) AND the Turn Signal tied together inside the mirror.

The GM factory intended operation of these mirrors is to have these Run separately.

Try removing pin 1 from the mirror hanress (in both sides) and see if their resolve the Turn Signal. Then, plug pin 1 back in. Remove pin 13 and see what happens.

Pin 1 is the running Lamp
Pin 13 is the Turn Signal.

My guess is these two are connected inside the mirror.

I opted for Phil's diy harness on my truck was willing to do the work myself and saved some money that way. The write up on it is step by step took me a couple hours including taping the harness back up with proper matching harness tape. I love when the Dealerships says no way and guys like Phil smirk and get to work, thank again Phil

Question...

 

I purchased the gm manual tow mirrors. Power and defrost. 

The mirrors i am replacing are the small power and defrost ones.

 

When replacing the harness will that be all i need to do? Or will I have to repin from the door back. I asked the vendor i bought the mirrors from gave my vin and he stated that i should not have to. 

 

Vin is as follows - 1GC2KVEG3FZ512281

Yep. Just replace the mirrors and harnesses. Hoping you got the right harnesses.

Which vendor did you get them from? Have part #s to share?

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      OCI, not when but why?

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
