Looking at available mirrors, I'm leaning towards some tow mirrors that are heated, power, have the rear facing LEDs I'm guessing for reverse and led on the front of the mirror that I'm not sure if they are only signal or marker or both.

 

I don't think I will bother with power fold.

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

The driving cost of the upgrade will be if you want power fold or not. The harness requirements or modification doesn't change between the two. Let me know if I can help in any other way. I am on vacation until 7/9, but accepting orders that will be filled after 7/9 upon my return, in the order they came in.

 

Thanks!

Once I get the mirrors I will get a hold of you to see what kit I need to buy so I can modify my harness. Cost wise, power fold is out. I'm in no rush, just bought the truck yesterday, lol. I'm guessing within a month I should get the mirrors.

Is it necessary to disconnect the battery before switching out the harnesses/mirrors?

Always the safe thing to do. There is constant 12V in the harness. I've had a fuse blown once. When I swap mine out, I disconnect the door jamb harness first which will remove power from the rest of the harness.

Man, this thread is amazing....lots of great info. I'm still debating my proposed change from DL3 to DQX but I'm getting closer. Phil, I don't expect or want an answer until you return from vacation!! I have a 2015 GMC 2500HD SLT manufactured 3/14 DL3 A45 but do NOT have AVF RPO code. Do I need the RZY additional harness? Are the High Ridge mirrors of good quality? Thanks!

I am still responding and taking orders :). Filling them upon my return on 7/9.

 

One way for sure to tell the requirements is by investigating the door jamb connector.

 

Take a look at this and let me know if Pins 9, 11, and 41 are present. Since you DL3s already, you should have pin 41. If you have all 3, this will be an easy upgrade and would only require my harness set.

 

As for Mirror Ridge, I haven't had the opportunity to try them. One thing to note about after market mirrors is that they might have their connectors pinned with custom hardwiring in mind.

 

I offer a service to correct this and make them PnP.

Mirrors have been ordered and should be here by the end of the week.

Currently have DL8 mirrors and the new tow mirrors have heat, power adjust, cargo lights and parking/marker lights. They are manual fold, manual extend and do not have the signals in the mirrors.

 

Once you are back, you can let me know what changes are needed and what do I need to purchase to make the conversion. Not looking fir complete harnesses, it will be DIY.

Just completed the DL8 to D3 conversion on my 2016 Silverado LT crew cab.

I also installed cameras in the mirrors, that will be hooked up to the MVI 360° camera system (once I install that)

 

Install took me 4hrs. Including the addition of the lane watch cameras.

 

Great upgrade!!!

I chose to purchase the harness that pgamboa offers.

It made doing this upgrade problem free.

Thanks again pgamboa !!!

I'll be sending you my DL8 harnesses.

PGAMBOA was very quick to respond and help me out with any questions I had regarding my mirror purchase prep. My confidence level went from 5 to 10 with a quick message. Very highly recommend his work if you need a set of harnesses.

My mirrors came in today and I didn't want to wait till I get what's needed to get everything functional. I'll pull apart the doors again later.

 

Driver's side mirror, power direction works properly. No cargo lights and no marker/signal lights on front of the mirror. No big deal for now.

Passenger's side mirror, power direction is a bit off,

Up is actually right,

Down is left,

Left is down and

Right is up.

Once they are set, I don't move them anyhow.

No lights on that mirror either, but again I expected that.

 

Once I know what's needed, I can order it and fix them. But for now, I have my visibility back, that I'm used to on the trucks I own.

If you can provide the mirror info (link) that'll be great to document. For the lighting, that is expected as the stock harnesses will not be pinned for the lighting portion. That's where my harness will come in and fix. Also need to know your truck Year and trim as the harnesses are built differently to accommodate the trim level. To correct the passenger motor movement, that should be simple by moving the pins around. Moving the pins on the mirror side connector are easy and I have a video for that. It would be good to note the pin # location and wire color for me to understand what's what.

 

I am on vacation but returning this Sunday 7/9. I have several orders to fill upon my return but shouldn't be backlogged too bad.

Not sure the link will work but here it is. http://www.ebay.ca/itm/142431734978

 

The truck is a 2017 Sierra SLE crew cab. Moving the pins in the connector should be easy for me, can probably do it with my eyes closed, lol. I was looking at just adding the required wires to get the lights working. I know you said you have a DIY option. What options are there for those lights. The rear facing LEDs are tied in with the cargo lights I believe. The front facing lights, are they marker lights or signals? That I'm not sure of. I think stock they use them as marker lights, but I'm am not sure if that is an option with my truck, or if the harness only allows it to be connected as a signal. I have weather tight connectors with all the pins and crimpers here at work that are commonly used on vehicles, but they all have round pins and I'm not sure if they are compatible with the connectors on the truck.

      Sugar Bears 2015 GMC Terrain SLE-2 2.4 AWD

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
