This is going to be the easiest and cheapest way to wire tow mirrors to have running lights and cargo lights plus all the other options on 20152018 gm trucks Silverado and Sierra. No need to buy an expensive harness or take it somewhere to get done.

*Note: If your truck did not come with signals on the mirrors, you will need to pin #41 with the red and yellow wire and then splice in the same place as shown in the video*

Got a lot of the ideas from this video, I just wanted to go more indepth.
