Adding POWER FOLD tow mirrors

[pgamboa]

 
 
Ok appreciate the quick response. Man I’m glad I found you! Thanks for taking your time to post and explain everything in such detail.
 
The last thing is......I guess I have to hope the dealer service department knows how to do this. Wonder if they have a manual or something they go by?

For the door harness swap, no. Just swap them out. They should be able to handle this.

If you need to add the RZY Jumper Harness - Part # 2387133, they should have access to that manual. Print this out in case. Lol. Feel free to direct them to my videos too. Lol. They may not like that and take offense. Lol

OK cool thanks again. Ha ha and you’re probably right, don’t want to get anyone mad!

As far as that RZY harness a.k.a. camper harness, maybe I’ll try checking the door harness this weekend and look for what you told me. Mine has a build date of 8/14 so I’d be willing to bet I probably do need that harness.

can I add power mirrors to 2020 GMC 2500HD Sierra with manual mirrors

[Adam1945]

I believe I understand everything thus far.
 

If I put in the OEM mirrors with power fold option how do I get it programmed by dealer, do I need the activation code?

 

can I drive vehicle with out flash for a while or do I need to get it programed right away( worried if I move mirror around it won’t be able to flash?)

And also what does the program do?

 

I have the 2016 diesel with original dl3 and memory for reference.
