I found this over at the Ram Body Builders Site, 2016, Electrical/Wiring Information, Upfitter Power Connector. I haven't looked but apparently this plug is located at the bottom of the B pillar.
I'm not an electrical guy but it appears that if I had the mating connector made by MTA, I could use these 2 wires. Pin 1: Is it hot all the time? Pin 2: What does Power Ground mean? Any other info to help me understand the possible uses for these 2 wires would be appreciated.
I mistakenly posted this over in the How-To forum and am re-posting it here.
