All the OEM's have taken so many pickles out of the jar they are selling empty jars and we are still buying them. What's to discuss?
Your handle and your beliefs seem a mismatch Kidding.
There are many failure modes and a few of them do show up early or not at all. Hardness for example. Others like cyclic stress failures, (valve springs not in coil bind but breaking anyway) are baked into the OEM cake. Those take a preset number of cycles which will be reached by different operators (miles). Load stresses are allot like cyclic stress but in the hands of a guy like me may never be exceeded while a guy who bought to use as advertised may get it to tap out on the first tow or haul or excursion into the offroad. There is a whole universe in between.
Until the death of the Buick 3800 and Ford 300 I-6 I used to believe that if you got it to 10K without a materials or lubrication related failure then how long it lasted was up to you and not the product. Today....not so much. They are building down to an ever reduced expectation driven by building down and there just isn't anything to be excited about.
The 2027 orders will be starting up soon, I'm surprised at how quiet these new engine discussions have become. Maybe it's because the HDs will still have the older 6.6 gasser until 2029 model year.
When 2027 GMC Sierra HD Production Is Scheduled To Start
The extra plug in connector servers two purposes - to connect the lighting circuits from the mirror to the factory connect. This will get you blinker on the glass only. That’s the factory function. That’s what you had before. The amber forward shining light behaves as a running light/park light - meaning it comes on when your headlights are on. If you outrun your headlight switch to park lamp mode, that amber would turn but (in a factory state). Your issue is that you’re not setup for tow mirrors. The door harness in your truck is wired different - so there is a path you’ll have to go down to either modify your door harnesses or replace them with a set and … since your truck is as 2014, add additional wiring inside your cabin of your truck that runs into the engine bay/fuse block.
So if you want to get these work, it can be done but will require some additional thinks and effort to get there.
