Installing tow mirrors

[Bigo1112]

First time poster here, recently bought some tow mirrors off of my buddy and installed them on my 2014 Silverado 1500 ltz, my stock mirrors have the light in the lenses for your blinker with heat, power adjust, memory, and power fold. I noticed the mirrors I got have 3 total connectors but my stock mirrors only have 1. I plug the new mirrors in and the only function I have is the power adjust. No lights no fold nothing. I’m guessing I need to wire something or repin the connector, any info out there on how to do so? The pictures attached include a picture of my oem connector with only 1 connector, and the aftermarket ones with 3 connectors. I apologize if I post this in the wrong section

what are the tow mirrors off?

Aftermarket mirror doesn’t support power fold or memory functions.  So key fob fold won’t work either. 
 

The two smaller connectors looks like they were disconnected. If you plug those two together, the blinker on the glass should work.  Amber light on the tow mirror will likely come on as a your old puddle lamp (so when you unlock at night - it’ll turn on).

Not so worried about folding or memory, but if that is the case I feel very dumb for not noticing that they connect to each other, so what you’re saying is the light in the back of the mirror will only light up when I unlock it? Or will it work with blinker too

Yep! This should be a pin somewhere as @pgamboa really dives into all of this.
Thanks for reposting the link!

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.
