Tried Google, but maybe I’m not using the correct words. Can anyone tell me what each of the connection ports control in the driver/passenger door module? I had to replace the side view mirrors on my (new to me) 2012 1500. The old mirrors had a black connector only, while the new mirrors had a black, and a white connector. I know black goes in number 2 (power mirror movement), and white into number 1. Just curious what port 1 controls so I know what switch to add.
