2018 sierra tow mirror upgrade?

[JQ]

Hi I have a 2018 sierra 2500 hd Z71.

I have mirrors with power heat turn signals and power fold. If I buy the factory tow mirrors for the truck do I still need new harnesses? The dealer told me I would loose my power fold and they would have to program the mirrors to the truck? Any help would be appreciated thanks.

No sir.  That is very inaccurate info.  If you get the correct mirrors, my custom hardnesses, you’ll retain power fold, memory, and won’t need any programming. 
 

Here is the link to my harness.

Many dealers will provision the wrong mirrors too.

Do not order the mirror kit they have as an accessory if you want to use using factory mirrors.  Those will NOT have power fold.  

 

You need the individual mirrors for RPO code DQS.  For black cap ones you need 84228899 left and 84228900 right for gas engine or 84691688 right for diesel engine.  

 

For chrome cap ones you need 84691681 left and 84228892 right for gas engine or 84691685 right for diesel engine.  

 

If you are diesel and install a right hand gas mirror you will get a check engine light.

probably a little late to the party but I bought tow mirrors from Boost Auto Parts and they are amazing, kept all my factory features and added some forward facing lights, they're expensive but I'd say they're worth it
