Looking to see if anyone has upgraded to the GMC mirrors with integrated turn signals and marker lights. My Sierra has the stock mirrors, heated and power only. Been to 3 dealers and no one can confirm if they GMC mirrors are plug and play. I had spoken to someone at GMC customer relations and they said the 2018 was pre wired for all the mirror options and the mirrors would work.

Does anyone have first hand knowledge of the wiring harness being able to support the new mirrors or what harness I need to get?

Thanks in advance for any information
