Thank You PGamboa for the door harnesses!! I now have all functions working on my DL3 mirrors. The first side was hard not knowing how the process should go. But the 2nd side was done in under 30 mins.
Installed the Chrome Skid Plate today. It took some time, but I would rather have did it myself instead of the $300+ my Chevy Dealership quoted me just for install ( parts not included). But it turned out great, and it completes the front end.
