mirror swap from tow to DL3

[papy]

Hello fellow GM members! I need to verify a few mods I am planning for my 2018 2500HD SLT

I am hoping some members can answer my questions.  I already messaged “pgamboa” as he seems to be quite active and knowledgeable with this swap.

I have a 2018 GMC sierra 2500HD SLT Z71 crew cab short box 6.6 L5P Duramax DIESEL

Currently set up from the factory with the towing mirrors. I am hoping to swap out the tow mirrors for the DL3 mirrors.

 

1.      The DL3 mirrors i need to order have to have the  “RPO Code - K40 Option (Exhaust Brake) for Diesel Trucks” as quoted in a previous post from pgamboa. No problem I can get them from my dealer

2.      I am told that I have to get new wiring harnesses for each side. I believe this to be true? Please verify.

3.      The most important thing tome are the options in the DL3 mirrors. From what I read in other posts and threads the puddle lights, power fold, heated mirror options should work with my SLT 2500 correct? Please verify

4.      The most important feature that i can’t find any info on is the auto dimming/shade Drivers side mirror. Is this something that will work on my SLT 2500 model? I don’t think my tow mirrors have the auto dimming/shade feature do they? I have yet to pick up the truck that is why I am asking.

5.      Is there anything I am missing? Is the rest just plug and play once I have the right DL3 mirrors and wiring harnesses?

I really need to know if all the features on the DL3 with RPO code K-20 mirrors will work with 2018 GMC 2500HD SLT Duramax DIESEL especially the auto dim/shade drivers side mirrors.

All and any info is appreciated

Thanks I advance

What was the model number for your existing DL3 mirrors? Also let me know if you still have your old tow mirrors I would be more than willing to pay for them.
