You can upgrade to tow mirrors but from what others have discussed on other forums is they are NOT plug and play for the power fold or turn signals but the heated and power adjust will work.

 

Also, You can NOT purchase any wiring harnesses to make them work. That has been confirmed so don't let the dealer sell you that stuff because most are out to make money and don't care if it works.

 

As you can see above that Ridculus is trying to sell his after attempting the same thing.

Take a look at this How To I just created. I just finished this upgrade and ran into the same issues you did. The reason why you lose functionality is because the harness you got is pinned out for t

Hey All, just completed the DL8 to DL3 mirror swap on my '15 GMC Sierra SLE. The magical door harness from the All Terrain exists. I bought a set of dl3 mirrors and door harness from a guy with a '16

Your tha man. That's exactly what I was looking for. Since you mentioned it auto dim on the drivers side mirror would be a pretty nice addition.. Starting to regret not getting the slt but I HAD to ha

Forgot to mention, the only option that were plug n play on the new mirrors were the default options I already had, power mirror tilt and heated mirrors. That is all the LT is wired for.

How much did it all cost? Curious so that I can forewarn others who are thinking of doing the same thing.

So, When you plugged the mirrors in using the STOCK wiring the turn signal part did not work?

It is plug and play on my 2013. My 2013 had everything the LTZ has with the exception of the power fold mirrors.

 

I guess if i buy a new truck next year I'll make sure that is added to the package.

 

 

Installing the mirrors and using a momentary switch mounted in a clean place on the dash and such isn't as big a deal as it sounds. Just use the diagram provided on the 1st or 2nd page.

That is correct. I traded in a 2013 Silverado for my 2014 because I loved the new technology, but the 2013 was much easier to work with than the 2014's are. Turn signals are no longer plug n play. You can look at the terminals in the connections to see the variance and see why its not plug and play. I dd intend to add a switch and wiring, I had this all throught my 2013, lot of car audio inside. But the 2014 they redesigned to be nothing like the 13's.

Mirrors I found for $500 used. Door switch DR was about $35. Harness was about $30.

Yes but people are already finding work arounds for mods. I'm sure someone has went through the whole thing but just hasn't shown up online yet.

RPO codes changed and wiring diagrams will be different for sure.

What does the switch look like? That's cheap, I think. ??

Well it is obvious the new mirrors don't fully plug-n-play onto the '14 Lt trucks but does anyone have a install for hard wiring the missing options and the color of what wires do what, a friend told me a shop was having difficulty doing it cause everything is working on a negative switching system, but someone out their has to know by now how to make them work with a few direct wire connections or at least explain the wiring.

The link I posted above should help as he pointed out what to look for in the plug.

 

Look at this or give it to the shop guys who understand it and this tells you where the connections are.

Also, You can pin out the BACK of the door harness plug using a test light to find which wires operate the turn signal

 

Even if the pin is not inside the plug the wires should be there but no pinned

I took some time to open the power fold mirrors I am selling, and put a multimeter to the wires in the connections to see where they went. Will post my findings shortly.

Well guys today I installed my new mirrors that come with signals and and power fold.

I bought the switch for the power fold and everything plugs in but the only thing that didn't work are the signals nor the puddle...

Has anyone done the entire thing.

FYI the power fold work without programming.

Hey there.. wondering if you could help me out with this. I have a 14 silverado LT with just power mirrors.. Can I pnp mirrors that are power, heated with turn signals.. or can I only upgrade to a mirror that is just power mirrors like what my LT came with?

I'm fine with just getting the powered tow mirrors dont need the heated or signals but it would be nice. . any if would rock

I have no clue on the 2014-15's about tow mirrors. Maybe someone will chime in or try YouTube

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

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
