Was there a final verdict on upgrading a WT? I have a new to me 2016 Sierra 2500 that came with newer mirrors that are not hooked up is my guess. The truck originally came with DE2 mirrors and somebody put on mirrors that have the blinker, running lights and side lights that I know of but none of it is working. I was needing to know how to tell what kind of mirrors I have now DPN or DQS and what I would need to activate them. I have pin 1, 2, 3, 9, 11, and 41.
Thanks for any help you can provide.
